1. which color of light is bent most in a prism?

Question

green, blue, red, violet, or yellow?

2. A material has an index of refraction of 1.75. What is the critical angle for this material?

a. 34.8 degrees

b. 16.7 degrees

c. 76.4 degrees

d. 55.0 degrees

e. 49.2 degrees

I don't know how to do this!?!? please help =)

It would be greatly appreciated! lols

Answer 1

1. Violet, since it has the least wavelength compared to others in the list

2. 34.8 degrees (not sure)

If i remember correctly, Crictical angle = Sine Inverse (1/1.75)

= 34.8

Answer 2

1. violet is bent the most

2. 34.8 degrees  using

    sine critical angle = 1/refractive index
