A) Snell's Law states n₁sin₁ =n₂sin₂. If the incident angle in air (n₁=1.00) to the normal is 35, what is the angle of refraction ₂ with table salt (sodium chloride) with an n = 1.544?

₂ =?

B) A ray of light moves from diamond (n = 2.42) to water (n = 1.33). Calculate the critical angle of total internal reflection of the diamond - water interface.

_C =
