Question

Suppose that white light strikes a surface of flint glass at an angle of 60 degrees. The index of refraction of this dense glass for red light is 1.710, for green light is 1.723, and for blue light is 1.735. What is the order of colors you would see in the refracted light? In the reflected light? From the surface up --

a.) Refraction: red green blue b.) Refraction: blue green red c.) Refraction: red green blue d.) Refraction: blue green red

Reflection: blue green red Reflection: red green blue Reflection: all the same Reflection: all of the same

Answer 1

ni sin(i) = nr sin(r)

sin(r) = sin(i) / n

i = 60 deg

smaller the value of n, greater will be reflected angle. so closerto the surface.

Red , green, blue
