Question
Resonance in an AC circuit is uniquely characterized by which of the following?
A. Minimum resistance
B. Minimum reactance
C. Minimum impedance
D. Minimum power output
Unpolarized light passes through a polarization filter oriented at 20° relative to the vertical. It then passes through a
second polarization filter, oriented at 80° from the vertical, in the same direction as the first. The intensity of light
leaving the second filter in terms of the initial intensity I, is
A. 1o
10/2
C. 10/4
B.
D.
10/8
A light ray travels from air into a medium with a refractive index of 1.7. Which of the following is true?
A. The ray refracts towards the normal of the boundary
B. The ray refracts away from the normal of the boundary
C. The ray only reflects off the boundary
D. It's impossible to determine with the given information
