There is nothing wrong with being scientifically literate, even though you will probably not remember any of it a year from now. It helps to try and figure out why it MAY be important in todays world.
dude i just want to say that you're the reason im passing, and also doing well in physics. You explain everything so well and clearly. I went from getting 3/10 on a quiz to getting 87.5% on a big test just 2 days later and every time since then as long as i use your videos to study I do very well. I can't thank you enough for them and the fact that its all free amazes me, so thank you!
+Jesse Daniel It is great that you are doing better and I am glad that you find the videos helpful. Thanks for letting me know. You can see a listing of all my videos at my website, www.stepbystepscience.com
YOU ARE AMAZING!!! (as i have commented on the other 4 videos!!!) thank you so much for putting in all this effort and time! you have helped over 40,000 people learn this subject! so on behalf of those who didnt comment; THANK YOU

I LOVE YOU THANK YOU SO MUCH. My teacher didn't explain this clearly. She just told us and as if we we're suppose to naturally memories this, like was I missing something... Thank you !
Thank you for making this video and the other for a concave mirror. My teacher didn't explain it well enough for me to understand it. This really helped!
Right after you did the diagram at f you said if the image is at 2f there is no image. 7:11 I saw in another video that you corrected your mistake. Thank you for making all of your videos, they have really helped me!
@Mark Uy, A convex lens is a converging lens, a convex mirror is a diverging mirror. A concave lens is a diverging lens and a concave mirror is a converging mirror. It is a little confusing to keep straight.
This video is very useful. This same thing was explained 4 times in school , but I didn't understood , but this help understood so easily......THANKYOU.......................
You are an amazing teacher!. You are a trillion times better than my physics teacher in school. I didn't understand it at school properly and then because of you I learnt it. Have an awesome day ahead 😊😊😁
THANK YOU SO MUCH IF IT WASN'T FOR YOU I WOULD GET LOW MARKS IN MY SCIENCE EXAMS BUT BECAUSE OF YOU I GOT EVERY LENS QUESTION RIGHT AND GOT FULL MARKS!!!!!!!! THANK U SO MUCH!!!!!!!!!!!
Thank you so much for this video! It wasn't very clear in class but this clarifies everything and explains it perfectly. I'm very grateful for this, thank you!
Thank you so much sir.... You explained all things so well that I will never be confused again. You teach 10 times better than my physics teacher. Thanks a lot again....
Hi Brian, I just wanted to say a huge thank you. I missed some class time and really didn't know how to do these until now. I think you saved me from failing my test tomorrow. Thanks again!!
hey wowwww, thank you so so so much..I'm a Physics students but never quite understood it, with your video, im getting the hang of the ray diagrams and all..
thank you it was really really helpfull i didnt understand this for a long time but after watching this the concept is crystal clear thank u!!!!!!!!!!!
@@stepbystepscience btw i was looking for a video about how to handle a object that starts immediately at a negative distance that is object_distance= -50 for example and how to draw a ray diagram in such a case, whilst having one convex lense! have you got one such video cause i looked throught and did not find such an example!
Its so interesting to learn when you understand.. Thanks a lot step-by-step science for teaching me physics so well or else I would have really failed...
Thanks a lot for publishing such a nice video, its a very admiring one..and has helped me understand a lot and also for removing my confusion for these lenses...
You are right about the location of the object and image (very good), but binoculars are not quite that simple. Binoculars and refracting (lens) telescopes use a combination of lenses to produce a magnified image.
Thnks A Ton Sir , I Was So Confused That I couldn't Understand Anything But then , I Went Through this Video And The Concept Became Very Clear To Me ! :)
Hi Mr. Swarthout, I'm grateful to see your videos, I just found them -- I'm studying for my CSET exams... I'm either missing something or just not seeing it -- At about 7:06 "... if the object is at 2f there is no image, because the rays are parallel..." -- yet the example shows the green arrow object is at f. Did I see & hear this correctly? I don't have a chance to read all history comments... I just want to make sure I am seeing the example/explanation correctly.
Maybe I said it incorrectly but....if the object is at 2f then the image will be at 2f on the other side of the lens, if the object is at f then there is no image because the light rays come out of the lens parallel...as shown in the diagrams. Does that help? You can see a listing of all my videos at my website, www.stepbystepscience.com
Thanks for the comment, It takes a while to put them together, space is usually and issue. You can see a listing of all my videos at my website, www.stepbystepscience.com
Kushagra Ratnam If you are try to actually draw the lens then pick a radius and put the pointer on two different points on the same line. If you want to draw the ray diagrams then you need a ruler and not a compass. I don't have time to make a video about actually drawing the lenses.
Thanks bro. I missed three days of class for AP exams and had no idea how to do these. My final quiz is tomorrow and you probably just stopped me from failing. :) Also thanks for discussing divergent rays, I couldn't find that info anywhere.
+Kovid Rupauliha Yes, things are not a complicated as they first seem. My goal is to explain things step-by-step….in fact...You can see a listing of all my videos at my website,www.stepbystepscience.com
@9:20 in the video, you explain about the magnified glass over a paper. Are we really seeing a "Virtual" image when we use a magnified glass over a text book/paper?
yes, you are seeing a virtual image, when you look through a concave lens you always see a virtual image (diverging rays) and when you look at yourself in a flat/plane mirror (think dressing room) you see a virtual image of yourself.
Light does not pass through any mirror (in theory), there are of course "two way mirrors". In the case of a plane mirror what you see is always a virtual image. The same is true for a convex mirrors, always a virtual image. For a concave mirror the image is virtual when the object is inside the focal point (the object distance is less then f). Hope that helps.
there is mistake at 11:08. image formed when object is kept at F is infinity. It is highly enlarged real and inverted. But you have given the comparison no image.
Actually I missed some of my class,, and I'm clear with ur way of fantastic explanation I just had a doubt so that I don't write or instead draw a unrelavent ray diagrams for my exam the day after ??? I'll be happy if u would be able to help me this stuff :-)

@Mark Uy, A convex lens is a converging lens, a convex mirror is a diverging mirror. A concave lens is a diverging lens and a concave mirror is a converging mirror. It is a little confusing to keep straight.
Ahhh! :) nice :D thanks for this :) I am sure I can differentiate now those two :) A lot thanks! :)
TT Its so hard its like alien words =_= I need to study more _ _ ,) the test is tommorow though...
thanks for ur video sir
A concave lens is a diverging lens and a {concave mirro}r is a converging mirror. it's concave mirror or convex lens

@9:20 in the video, you explain about the magnified glass over a paper. Are we really seeing a "Virtual" image when we use a magnified glass over a text book/paper?
yes, you are seeing a virtual image, when you look through a concave lens you always see a virtual image (diverging rays) and when you look at yourself in a flat/plane mirror (think dressing room) you see a virtual image of yourself.
There is no light passing through it in case of a plane mirror. Right? That is why we call our own image as a virtual image. CMIIW.
Light does not pass through any mirror (in theory), there are of course "two way mirrors". In the case of a plane mirror what you see is always a virtual image. The same is true for a convex mirrors, always a virtual image. For a concave mirror the image is virtual when the object is inside the focal point (the object distance is less then f). Hope that helps.
