The critical angle for an air-glass interface is 10.9 degrees. A ray in air is incident on the interface. The reflected ray is 100 percent polarized. The angle of refraction is closest to:
A) 10.7
B) 10.1
C) 9.51
D) 8.91
E) 8.31
Question 2
A parallel-plate capacitor, with air between the plates, is connected across a voltage source.
This source establishes a potential difference between the plates by placing charge of magnitude
4.15 x 10-6 C on each plate. The space between the plates is then filled with a dielectric material, with a dielectric constant of 7.74. What must the magnitude of the charge on each capacitor plate now be, to produce the same potential difference between the plates as before?
