Express answers to the correct number of significant figures. Points shown in red. The relationship between the speed of light (c), frequency (f), and wavelength ( 8 ) is: c = f 8 c = 2.998 x 10 8 m/s. 3 1. If 8 = 555 nm, what if f? 3 2. If f = 6.76 x 10 14 Hz, what is 8 (expressed in nm)? The index of refraction is defined as: 3 3. n Chloroargyrite = 2.07. What is the speed of light in chloroargyrite?

Unformatted text preview: , _ 2 4 4. If light travels from air into sylvite, and the angle of incidence is 29.6°, what is Ê r? n for sylvite = 1.490. Brewster’s Law of maximum polarization is: 4 5. For sylvite, what is Ê i? The critical angle is given by a variation of Snell’s Law: 4 6. Suppose light passes from sylvite into air. What is the critical angle? HINT: Remember that light is going from sylvite into air. What is the incident medium? The formula for the Numerical Aperture (N.A.) Is: 4 7. If the angular aperture is 35.7°, and n = 1.544, what is N.A.?...
