I will probably never use this in my life, but I still have to learn it.

It's fun studying when you understand the lesson. I wish teachers explain like this, brief and straight to the point.

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!

Out of all results of my searches, you're the one who helped me really well. 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!

I hope there are teacher like you in all school over all the world, you're the best

This video is very useful. This same thing was explained 4 times in school, but I didn't understood , but this help understood
so

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
THANK U SO

[mrs.willette]

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.

Great presentation by a very competent host whose voice neither grates nor anesthetizes the listener

[khalilomar]

thanks. my teacher took a whole week trying to explain this but barely understood. 12 min video made me understand it.

[jeremiahalphonso]

Probably the best explanation i have seen in my life

[aakifjaved]

Thanks Sir.Not only were your videos extremely helpful but also so detailed that I find it the best video on the web.Thanks once again

[VaultDwellerOG]

Videos like this are better than most high school teachers. I learned something.

[simoneoliver]
