12. Imagine playing golf in a world where the speed of light is only 3.4 m/s. Golfer A hits a ball down a flat
horizontal green for a distance that he measures as 75.0 m. Golfer B, driving in a cart, happens to pass by
just as the ball is hit. Golfer A stands and watches while golfer B moves along the green, beside the ball at
a constant speed of 2.8 m/s.
a) Which golfer will measure the proper time interval for the motion
of the ball? Justify your response (no calculation necessary).
Golfer A
Golfer B
b) Which golfer will measure the proper length that the ball travels? Justify your response (no calculation
necessary).

This phenomenon is called the Cerenkov effect. When a nuclear reactor is shielded by a large pool of water, Cerenkov radiation can be seen as a blue glow in the vicinity of the reactor core due to high-speed electrons moving through the water as shown. In a particular case, the Cerenkov radiation produces a wave front with an apex half-angle of 53.0°. Calculate the speed of the electrons in the water. The speed of light in water is 2.25 × 108 m/s.arrow_forwardMake a general statement comparing the speed of light with the speed of sound.
