Bro I love you. Physics test tomorrow. No such thing as sleep tonight. You are amazing this is soooooooooooo helpful. Please be my tutor for college. Again, thanks man you are awesome
+Sachin Kumar Thanks for the comment, I love you tooooooo. Unless yur college is in Berlin Germany the tutoring thing might be kind of difficult. Oh well.... You can see a listing of all my videos at my website, www.stepbystepscience.com
thank youuu so much sir. i just watched your concave mirror ray diagram and it really helps me. i really learn a lot and so i proceeded to check your convex video. thank you again
Just letting you guys know I use an acronym called SALT for this. S: Size A: Attitude ( facing up or down ) L: Location T: Type (Real, Virtual) if that helps any of you out there 👍🏼
They are the same thing, the point where the rays converge or appear to converge. FYI....The focal length is the distance from the focal point to the lens or mirror.
ady singh it means you're too late to reply because I already passed grade 10 science with a 97 and right now im in grade 11 physics so instead we should talk about why the hell I'm getting a 62.
thank you so much!! this helped me a lot for my report, you just saved my grades that are at risk. (you're so great at explaining things😭) thanks again!
Thanks for all your time n effort making these extremely helpful + well-organised videos! I watched them and understand so much faster and easier than just by reading the textbok! Thanks for helping and teaching us!!!
+Laura Suris As you noticed it is not really that complicated, everything just needs to be explained step by step. You can see a listing of all my videos at my website, www.stepbystepscience.com
Thanks for the comment, yes I try to get right to the point and then stay on it. You can see a listing of all my videos at my website, www.stepbystepscience.com
Yes and I live in Berlin. I would say read children's books, watch UA-cam vidoes for simple Deutsch, then move to a German speaking country. Viel Erfolg!
I love your videos, they help get a better understanding. Would you be able to make a video on calculating the characteristics like do, di, hi, etc. on lenses?? please and thank you
Nada Youssef I made video for using the thin lens equation and doing all of the calculations. here is a link to one of them. ua-cam.com/video/u4zhWFALZ-Q/v-deo.html
+pink cookie princess Yes, as the object gets closer to the lens the image gets bigger. When the object is at the lens then image and the object are the same size are the same size. Draw a couple of ray diagrams and prove it to yourself. You can see a listing of all my videos at my website, www.stepbystepscience.com
+Peter Pachis Great question, You only need to draw two lines, the image will appear where they intersect. You can always draw more, a third, to confirm that you drew the first two correctly. Sometimes it is a little harder to draw the third if your overall sketch is not to scale. You can see a listing of all my videos at my website, www.stepbystepscience.com
thank you for the comment, the videos are made with keynote and recorded directly on my computer with quicktime. In the past I have also use Screenflow an screen capture program for the Mac. It records what is on your computer screen and what your computer camera sees. But I do not have it on my current Mac.
Question: the Eye is also a lens. You aren't accounting for the direction of the light once it passes through the eye lens.... why not? and does that change the results?
Thankuu sir but I have.a question when u incident a ray a little bit above 0 what is the range for the light ray it will go parlell when it is incident on lens.
If you put the object "in front" of the lens then it would be on the same side as you and the lens would not do anything. or am I nor understanding your question.
@@stepbystepscience thank you sir, i understand with your explanation. Yesterday, when I still learn about lens, I saw another video said, the object can put in front of the lens or what i mean in the virtual condition. Before that, I never heard that condition.
And until now, he didn't answered my question, "Why you can put images in front of the lens or in the virtual condition? And I asked her explanation what the application in the daily life when he put object in the virtual condition at concave lens?"
Lee Yong Ee I am sorry I don't quite understand your question but for lenses you can just extend the center line of the lens and use that line for your refraction. In this case if the lens is too small or the object is too big you can use the line to locate the image. You can use the same concept for the mirrors as long as you follow the ray drawing rules. Sorry I know that is a bit vague.
Brian Swarthout Sorry I forgot to mention I was asking about the convex mirror. What if I apply it in a real case which I know the actual dimension of mirror and I need to find out the maximum area that the mirror can cover? How should I determine where is the limit of coverage?
5:37 Convex mirror
In case anyone needed the timestamp
You are legit going to be saving my life. I’ve got an exam tomorrow, and I don’t know this stuff!!
My MCAT is in 15 days and I had pretty much given up on the physics problems until I found your channel. Thank you for your videos!
Thanks Brian Nobody Here Have commented on this video But U R A very Good Instructor THNX FOR THE VIDEO
Thanks... I have a test tomorrow and this helped a great deal... You're so much better than my school teacher
Sorry that I am so much better then your teacher. Hope the test goes well!

You are most welcome and thanks for the comment!
Thanks man for the video! Saved me an hour of reading
Just letting you guys know I use an acronym called SALT for this. S: Size A: Attitude ( facing up or down ) L: Location T: Type (Real, Virtual) if that helps any of you out there 👍🏼
nice! got any tips for memorizing the info?
My teacher uses LOST L-LOCATION O-ORIENTATION S-SIZE T-TYPE
You just saved my final exam score! Thank you very much sir!!
Great, hope the final went well! Thanks for the comment.
I think this is the best video I have watched about lenses. Thank u very much for making such types of videos
They are the same thing, the point where the rays converge or appear to converge. FYI....The focal length is the distance from the focal point to the lens or mirror.
my teacher put PF and SF (PF on the left, SF on the right) and doesnt have any points after that. what does this mean?
MrMysteryy it means ur mam needs to revise the topic.
ady singh it means you're too late to reply because I already passed grade 10 science with a 97 and right now im in grade 11 physics so instead we should talk about why the hell I'm getting a 62.
Step-by-Step Science Very thanks for ur help it's easy to understand
In a concave mirror, when the object is on C will the image always be the same size?
thank you so much
saved my physics part in science exams
thank you so much!! this helped me a lot for my report, you just saved my grades that are at risk. (you're so great at explaining things😭) thanks again!

This is very helpful for my studies
Great!
do you mean a convex mirror by itself or a convex mirror video by itself. The answer to the first part is yes and the answer to the second is no.
+Brian Swarthout what is the difference between focus and the focal point?
Step-by-Step Science nicevid!
All of your optics videos are great! Thank you! Great MCAT study tool.

You are very welcome
I got a perfect score because of this thanks so much
@@kimhyesung7180 That is great, thank you for letting me know and I am glad that you did so well.
If you move the object closer to the concave lens does the virtual image become bigger or smaller (than the former one)?
+pink cookie princess Yes, as the object gets closer to the lens the image gets bigger. When the object is at the lens then image and the object are the same size are the same size.

Why do some times you draw 2 lines and other times 3? Like for instance at 8:58 you draw three.
+Peter Pachis Great question, You only need to draw two lines, the image will appear where they intersect. You can always draw more, a third, to confirm that you drew the first two correctly. Sometimes it is a little harder to draw the third if your overall sketch is not to scale.

Great video and warm accent. I just ask my students to follow the video and it's done. Could you tell me what software you used to draw things?
It is just Keynote from my MacBook Pro. Thanks for the comment.
Your videos are great thank you so much, may I ask what software and hardware you use to make your educational videos ?

draw a ray diagram using concave lens forming an image
thank you very much ..
this is very useful to me
Thankuu sir but I have.a question when u incident a ray a little bit above 0 what is the range for the light ray it will go parlell when it is incident on lens.
In concave lens at all points do we have to make the rays in that way which you showed
Anushka Mittal Yes
Can i ask how to identify if what is the 1 ray, 2 ray ?
The rays are not really identified as 1 or 2, you can do them in any order you want.
the explanation the image is very helpful . but what about the ray diagram when the object is at infinity ??
U are a legend
I wish...but thanks for watching and commenting.
