Physics: optics of lenses and mirrors (5)

Physics: Introduction to the optics of lenses and mirrors. Concave, convex, converging, diverging; real, virtual; upright, inverted, magnified, shrunk. Sign conventions for focal length, image distance, object distance, magnification. The lens/mirror equation; the magnification equation. Introduction to ray tracing.

omg. You are AMAZING. And that falls short to describe how helpful you are. I have struggled with physics all my life, since high school, community college, university. Now that I have graduated and I am studying for graduate school admission's exam, I have gone back to try to understand this material. You have helped me understand physics. Thank you so much!!!!!

awesum!!!

[MrVrokks]

where can I find videos which explain solving problems with examples.

Thanks for any advice

maybe our state should rethink education budget cuts - case and point

@NevilleRhysBarnes and im 15, just goes to show what a wide range he is educating!

honestly khan is great and i think wat he does is awesome for regular or honors hs courses but this is awesome cuz u go much more in depth and always start from fundementals

Amazing Job, You've helped me a lot and i really like the way you go about explaining things and then slowly putting all the pieces together and checking back after each piece to check understanding. One thing i noticed that may help the student out a bit when it comes to converging/diverging is to ask him to look at the light ray's angles coming from the outgoing light and comparing them to the incoming light. If their angle between them decreased during the outgoing light it is a converging.

Very useful. (I am 52 and studying physics with the UK's Open University.)
