Light containing wavelengths of 400 nm, 500 nm, and 650 nm is incident from air

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 of22.5 degree. (a) Are all colors refracted alike, or is one color bent more than the others? 400 nm light is bent the most 500 nm light is bent the most 650 nm light is bent the most all colors are refracted alike correct check mark (b) Calculate the angle of refraction in each case to verify your answer. theta 2 = 2correct check mark degree (400 nm) theta 2 = 3wrong check mark Your answer differs from the correct answer by 10% to 100%. degree (500 nm) theta 2 = 4wrong check mark Your answer is within 10% of the correct value. This may be due to round off error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize round off error. degree (650 n

Explanation / Answer

   sin i / sinr         =      n    sinr   =   sin i / n    => sin2   =   sin 22.5 /1.52   =   0.252       2   =   sin-1( 0.252)   =   14.580    Similarly            sin3   =   sin 22.5 /1.51   =   0.253    3   =   sin-1(0.253)   =   14.680    Similarly            sin3   =   sin 22.5 /1.51   =   0.253    3   =   sin-1(0.253)   =   14.680
