I have never been good at doing this in physics so I want to make sure I'm doping this right. The question asks:
What units would result from each of the following calculations?
a) 3cm/s x 25s
b) 4m2 ÷ 6s
c) 15m/s2 x 2s
d) 5m/s ÷ 3s
e) 3g ÷ 2cm3...
So for a project I am asked to give examples of how cameras are used. Of course the obvious use is clear, but how else (hopefully physics involved ways) are cameras used?
Forgot to mention, my project is on photographic not digital cameras.
Yeah, you are right that's total internal reflection. I can't change the index of refraction because it's a question in the assignment. It's kind of like it is what it is because the question was written that way (hope you know what I mean). Anyway thanks for trying to help ;)
The index of refraction is not meant to be correct, it probably just made up. With Snell's Law I was able to find the angle of incidence, but I don't know what to do next. Also I thought the angle of refraction had to be at least 90° for there to be reflection, that's why I'm stuck.
Doc Al, I know Snell's Law and the law of reflection, but still can figure how to get the angle of reflection. I asked this with knowledge on the topic so your answer didn't help whatsoever.
I have an assignment to due and it asks for the angle of reflection, but I don't know how to get it. This is the question:
"A beam of light is directed on the flat surface of a block of fused quartz (n=1.92). Part of the beam is refracted with an angle of refraction of 30°. What is the angle...
