The Tunguska event refers to a meteor impact on June 30, 1908. On that day, a meteorentered the Earth's atmosphere, burned up, and exploded in the air above the TunguskaRiver valley in Russia. It knocked down trees over thousands of square kilometers andstarted a forest fire, but produced no crater, and apparently caused no human casualties.A witness sitting on his doorstep outside the zone of falling trees recalled events in thefollowing sequence. He saw a bright light moving in the sky, descending towards Earthat a low angle to the horizon. Suddenly, he felt his face become warm. Then, he felt theground shake. Next, an invisible force threw him about a meter away from where he wasseated. Finally, he heard a very loud rumbling sound. What types of waves are involvedin each of these observations? Explain why these events happened in the order described.

How long should it take the voices of astronauts on the Moon to reach the Earth? Assume that the only significant time is the transit time from the Earth to the Moon, at the speed of light. Suppose that the astronaut on the surface of the Moon, the receiver on the surface of the Earth, and the centers of the Earth and the Moon are aligned. The distance between the centers of the Earth and the Moon is 384×103km, the radius of the Earth is 6.38×103km, the radius of the Moon is 1.74×103km.

Consider a spiral galaxy that is moving directly away from Earth with a speed V = 3.040×105 m/s at its center, as shown in the figure. The galaxy is also rotating about its center, so that points in its spiral arms are moving with a speed v = 6.950×105 m/s relative to the center. A) If light with a frequency of 7.543×1014 Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving toward the Earth? (Measurements of this type are used to map out the speed of various regions in distant, rotating galaxies.) Express your answer using four significant figures.

A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 576.6 nm had been shifted to green with a wavelength of 562.3 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits. answer in m/s
The spectrum of a star is used to measure its radial velocity with respect to the Sun, the component of the star's velocity vector that is pa rallel to a vector connecting the star's centre to the centre of the Sun. The measurement relies on the Doppler effect, in which rad iation is shiftedin frequency when the source is moving towards or away from the observer. When a star emitting electromagnetic radiation of frequency v moves with a speed s relative to an observer, the observer detects radiation of f requency vreceding, = vf or vapproaching = v/f, where f = {(1 - s/c)/(1 + s/c)}1/2 and c is the speed of light.
