6 In a Michelson interferometer, a shift of one interference fringe corresponds to a change in optical path length of:

A Half a wavelength
B One wavelength
C Two wavelengths
D One quarter of a wavelength

7 Which type of optical aberration is characterized by the inability of a lens to focus all wavelengths of light to the same point?

A Spherical aberration
B Coma
C Astigmatism
D Chromatic aberration

8 The polarization of light by reflection from a non-metallic surface, as described by Brewster's Law, occurs when:
