Light enters an equilateral triangle prism in a direction parallel to one side. the prism is made of glass with an index of refraction of 1.52. what is the angle between the incoming ray and the ray that leaves the prism on the other side?

31.2 degree

Explanation:

Angle of prism, A = 60 degree

refractive index, μ = 1.52

The angle between the incident ray and the emergent ray is called angle of deviation δ.

The angle between the ange of deviation and the refractive index is

δ = (μ - 1) A

δ = (1.52 - 1) x 60

δ = 31.2 degree

the answer is b i think

this could be newton#'s law of cooling. the cooling curve is exponential
