Question

Light containing wavelengths of 400 nm, 500 nm, and 650 nm is incident from air on a block of crown glass at an angle of 48.7°. (Assume crown glass has refractive indices of 

n400 nm = 1.53,

n500 nm = 1.52,

 and 

n650 nm = 1.51.) (a) Are all colors refracted alike, or is one color bent more than the others?
400 nm light is bent the most500 nm light is bent the most    650 nm light is bent the mostall colors are refracted alike
(b) Calculate the angle of refraction in each case to verify your answer. (Enter your answer to at least two decimal places.)
𝜃400 nm =  ° 𝜃500 nm =  ° 𝜃650 nm =  °
