The index of refraction determines??`?

Question

a) the angle of refraction; based on the angle of incidence
b)the angle of refraction, based on the angle of reflection
c) the angle of incidence, based on the angle of refraction
d) none of the above. The angle of refraction is a constant for all mediums

Answer 1

"A" is more reasonable

Answer 2

I believe the answer is a, but I definitely know that its not d because the angle of refraction is not constant for all mediums but rather depends of the medium itself.

Answer 3

"a" is correct. However, even "c" is correct too. It is the ratio between the angle of incidence and angle of refraction. So, if one of them is known, then the other could be found using the "index of refraction".

Answer 4

see:
http://en.wikipedia.org/wiki/Snell%27s_law

Angle of incidence is not necessarily unique for some angles of refraction. That's because angles of incidence exceeding the critical angle results in total internal reflection:

Answer 5

It is answer A since
index of refraction = sin(angle of incidence) / sin(angle of refraction)
or for short: n = sin i / sin r

Answer 6

We shine easy incident on the air-block interface that's at a prevalent perspective relative to actual perpendicular. We then degree the perspective of refraction. With the prevalent refractive index of air (infrequently even worth stressful approximately that it truly is somewhat greater suitable than one) and the two prevalent angles, the equation of Snell's regulation would be relatively solved for the unknown refractive index of the plastic. As for the fee of sunshine in the plastic, merely use the definition of refractive index, and you will see, undeniable as day, a thank you to unravel for the fee of sunshine in the plastic.

Answer 7

Do not quote me, but A sounds right.
