A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red light of wavelength 650 nm appear green to him, with a wavelength of 520 nm. The police officer writes out a traffic citation for speeding. How fast was the physicist traveling, according to his own testimony?
In the “red shift” of radiation from a distant galaxy, the light Hy, known to have a wavelength of 434 nm when observed in the laboratory, appears to have a wavelength of 462 nm. What is the speed of the galaxy in the line of sight relative to the Earth?

How long does it take light to travel from the Earth to the Moon? The speed of light is 2.998×105 km/s and the Moon is 3.844×105 km away from Earth, on average.
A person on earth communicating via radio transmission with an astronaut on the moon asks a question. At the time of transmission the moon is 4.00 x 10^5 km from the earth, and the speed of radio waves is 3.00 x 10^8 m/s. How long must the person on earth wait for a response if the astronaut answers 2.50 seconds after the message is received?
The speed of light is c = 3.0 x 10^8 m/s. If the distance between the Earth and the moon is d = 2.39 x 10^5 mi (1.0 mi = 1.61 km). You send a laser from the Earth to the moon and back. How long does this take?
If the distance from an antenna on Earth to a geosynchronous communications satellite is 26000 miles, given that there are 1.61 kilometers per mile, and radio waves travel at the speed of light (3.0 x 108 meters/sec), how many milliseconds does it take for a signal from the antenna to reach the satellite?

Neil Armstrong was the first man to walk on the moon. On July 20, 1969, his famous statement, "That's one small step for man, one giant leap for mankind." was received at 10:56 p.m. ( EDT) on Earth. (a) How long I did it take his voice to reach Earth via radio waves? (b) At what time (in EDT) did he utter this statement at the surface of the moon. The distance between the Earth and the moon is 3.85 x 10⁸ m.

The intensity of light I through a lake at a depth of x meters is given by the following formula. dI/dx = (-2.31)I a.) At what depth is the intensity of the light half that of the intensity at the surface, I00? b.) At 5 meters deep, what is the intensity of the light as a fraction of I0? c.) How many meters deep will the intensity of light be 1 percent of the intensity of the light at the surface? Remember that the depth at the surface is x = 0.
