QUESTION 14
When certain light rays pass from a vacuum into a block of an unknown material, the measured index of refraction of the material is 1.59 What is the speed of light
inside the block?
2.9 x 10° m/s
4.8 x 10 m/s
9.9 x 106 m/s
1.9 x 10° m/s
1.0 x 10° m/s
The speed (V) of light in any transparent material is less than the speed of light c in a vacuum:
V (any transparent material) = c /n, c = 3 x 10 8 m/s, n = index of refraction of a transparent material
What is the speed of light in alcohol? nalcohol = 1.36
The speed of light in a vacuum is 3 x 108 m/s. What is the ratio of its speed in water (n = 1.33) to its speed in a vacuum? Enter your answer as a percentage
