Physics: optics of lenses and mirrors (9)

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.

its the 9th video and yet the student said its a REAL image

haha its funny to look at the view count on the first video and as we go along less and less ppl watch it ^^

@PurpleCl0ver That's not really because these aren't as good. It's just that many people only need the beginning information and can go on on themselves afterwards. I skip parts myself. Not because he's not good at explaining , but because I don't need the slow pace. (Which is really not meant offensivly, it's a great thing).

I smoked a lot of weed in high-school too

Great videos. My favorite part however is the fact that the student is yet to get a single answer correctly. Since each question only has two possible answers, he would do better flipping a coin!

@wardamk1 well i prolly would have messed up a lot too-- we have an advantage in a sense that we can pause and re-watch or rewind to remind ourselves of some of the properties...but i bet a lot of us watching including me would be less confident actually in his presence xD

@freelanceteach

what if the object is at f or at 2f?

[rabia20086]

@wardamk1 i know its soooo funny...i just tink he needs more healp....awwww bless
