Transcribed Image Text:4.
Imagine that two very smooth glass plates are stacked on top of
each other sounded by air. The first plate has an index of refraction
of 1.4, while the second plate has an index of refraction of 1.7. A
light ray is incident on the top surface of the first plate at an angle
e. What is the speed of the light ray through the top plate?
A. 2.1x108 m/s
B. 2.6x108 m/s
C. 0.8x108 m/s
D. 3.0x108 m/s
5.
Refer to the scenario in question #4. The sine of the critical angle
for the light incident on the bottom of the lower plate is:
A. 0.71
B. 0.97
C. 0.84
D. 0.59
6.
Again, refer to the scenario in question #4. Compare the angle 8 to
the angle of refraction in the lower plate.
A. It is bigger
B. It is smaller
C. It is the same
