Using filters, a physicist has created a beam of light consisting of three wavelengths: 400 nm (violet), 500 nm (green), and 650 nm (red). She aims the beam so that it passes through air and then enters a block of crown glass. The ' beam enters the glass at an incidence angle of0₁=40.2.

The glass block has the following indices of refraction for the respective wavelengths in the light beam.

wavelength (nm) 400 500 650

--------------------------------------------------------------------------------------------------

index of refraction

n_{400 nm}= 1.53 n_{500 nm}= 1.52. n_{650 nm}= 1.51

(a)Upon entering the glass, are all three wavelengths refracted equally, or is one bent more than the others?

Pick one

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

(b)What are the respective angles of refraction (in degrees) for the three wavelengths? (Enter each value to at least two decimal places.)

(i) (degree)_{400 nm. _____}

(ii)(degree)_{500 nm. ____}

(iii)(degree)_{650 nm. ____}
