Using filters, a technician has created a beam of light that
consists 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 of 𝜃1 = 40.6°.
The glass block has the following indices of refraction for the
respective wavelengths in the light beam.
n400 nm = 1.53
n500 nm = 1.52
n650 nm = 1.51
1. (Multiple Choice) __?__ (a, b, c, or d)
Upon entering the glass, are all three wavelengths refracted
equally, or is one bent more than the others?
(a) 400 nm light is bent the most
(b) 500 nm light is bent the most
(c) 650 nm light is bent the most
(d) all colors are refracted alike
2. (not multiple choice) What are the respective angles of
refraction (in degrees) for the three wavelengths? (Enter each
value to at least two decimal places.)
(2a) 𝜃400 nm
___?___ °
(2b) 𝜃500 nm
___?___°
(2c) 𝜃650 nm
___?___°
If you could label the answers for 1., 2a, 2b, and 2c, that
would be great, thank you very much.
