Jetzt bin ich in Berlin aber ursprünglich aus California. Jut, dass Sie die Videos hilfreich gefunden haben. Danke für die positive Bemerkung und viel Erfolg bei der Prüfung.
This video is really really very useful.I also watched many videos about concave and convex mirror but i didn't understand but after watching this i totaly understand this topic. Thank very much for this amazing explanation ❤🙂
Even after listening to class lectures and class videos I didn't understand virtual images but this video made a lot of sense with the dotted lines representing what we see. Thank you so much for making this.
I wish to thank you personally for these videos. I teach underprivileged children. I used these videos using my tablet to explain to these kids who do not have access to a laboratory. My student passed his 10th grade in flying colors and and did well in physics thanks to videos like this. You made someone's life...Thank you once again and keep up the good work.
Parvathi Vaidyanathan The pleasure is all mine. I am very happy that you and your students have found the videos to be helpful. Thank you very much for commenting. I recently put together a simple website where you can find all of my videos listed by topic, www.stepbystepscience.com
Very good explanation, I got it the first 10 seconds I watched the video because I was confused on lenses and mirrors. But you put them right next to each other which instantly cleared it up. Thank you!
Thank you! I'm a biology teacher studying for a general science certification test. Physics was never my strong point, and it's been over 10 years since I took a physics class. This was very helpful for my studying!
This simply explains it all :) Thanks for this great video :) it really help me a lot. Iam a bit confused until I watched this video. It is so clear now :) Thanks again. Iam from the Philippines :)
From Germany? Toll!! Vielen Dank für Ihre hilfreiche Video.. I'm from New Zealand sitting my year 12 physics ncea exam tomorrow.. Your video was very helpful for revision!

I think most of us can really develop to be brilliant if taught well. Iam a mature age student doing engineering this year and find our online uni lecturers to have no talent or purpose, sorry to say. Very refreshing to see people like yourself really care about the thought process of the student and try and connect with it.
Thank you very much for the video; it was explained clearly with a good presentation. This was a really confusing topic for me but this video cleared up my doubts. Keep up the great work!
Great question, one that I had not thought about, As the mirror gets flatter the focal gets longer and as the mirror gets more curved the focal length gets shorter. So in order to have the focal point on a concave mirror it would have to be a single point, same thing for a convex lens. I think? What do you think?
Thanks so much for this video. Seeing the images formed by the lenses and mirrors in reality was most helpful. Overall this video helped me understand better and not just memorize.
This some quality education right here. I'm no joke impressed my! My physics teacher didn't show us how similar convex lenses and concave mirrors are and like wise with concave lenses bs convex mirrors.
Well I'm a little irked with my teacher now that I know how simple it all seems to be, now. Through all the over-complications, I hadn't understood much in the classroom. Thank you for making it concise yet informative!~
***** Most things are really somewhat simple and can be simply explained. I always try to go step-by-step. Thanks for the comment….you look good in pink!
I'm from Australia, I just want to thank you for making this video. I kind of skimped out of studying and my test is tommowow (yr.9), this helped me a lot, don't get me wrong I'm good at science, best in my class. But this stuff was confusing me, thanks for the help and know you have friends from down under!! 😃😃😃
Good question, but......The light does not "assume" that it comes from the focal point. When it passes through a concave lens it is always refracted in such a way that if you trace the rays back behind the lens they will meet at a point behind the lens. This point is called the focal point.
Absolutely amazing! Thank you so much for sharing this with us! If people are saying it is boring ^^^ then they should not be watching only to give negative feedback! I love to learn - they obviously do not! I appreciate this! :)
My concept of lenses and mirrors are crystal clear, its so well explained. Thanks for sharing this very helpful in information, its really helping me study for a very important upcoming test. =D
amazing ... its was the topic that I felt I cannot do it and its most confusing .. but Sir Your explanation helped me not only to understand the concept but cleared doubts and boosted me to do it ..Thank you for Sharing
Assasin Pro Thank you very much for the comment, for this one I used my MacBook Pro, Keynote and Screenflow and screen capture program that lets me record from a Webcam and what is on my desk top at the same time. Then when editing I can switch between them as desired.
Thank you much for this video. I am enlightenend more... If you can discuss more about the image(s) formed when the image is within the focal point and on the focal point, that would be very helpful to me or us... God bless you!
Thank you for this. I thought I was a bad listener but my teacher is just really bad at explaining things. We studied light for a while yet I still could not identify a concave and convex mirror.
Can you please clarify on what the focal point is? I am quite confused lol. So do you need the focal point in order to see? If so, then how does the eye see the image in the first place if the light does not pass the focal point at the beginning. Or does the eye just receives the light traces it back to the origin?
Thank you very much. I have a question . Where is the focal point? . what is the distance between the focal point and lens or mirror? , or is there any ratio?
Thanks for the compliment, I try to be as clear and step-by-step as possible and sometimes wonder if I am being too boring….also I am not a professor, but I do play one on UA-cam…in reality I am just a high school science and math teacher living in Berlin Germany. Have a great day.
So after some thought I feel as though the answer to my following question is no, but its better to ask you anyway. Is it possible to have a Convex lens or concave mirror where the focal point is on the lens / mirror itself? I feel as though this would mean that the mirror / lens is a line...

Great and thanks you so much for much for commenting.
you are one of my favorite UA-camrs! never failing to simplify concepts
I try to explain everything step by step. Thanks for the comment.
I can now pass my physics class!! THANK YOU!!
Great, hope it goes well, thanks for letting me know!
thumbs up well explained i think instead of attending school we should attend youtube...daily
yes, you can learn it all on your own. Thanks for the comment.
you really deserve thumbs up and thanks My pleasure
