Quiz_09 Relativity simultaneity, time dilation, length contraction Physics 274 9/14/2016
Q1 As a high-speed spaceship flies past you at half the speed of light, a strobe light fires at the center of a room aboard the spaceship. As measured by you, the light from the strobe A. reaches point A before it reaches point B. B. reaches point B before it reaches point A. C. reaches points A and B simultaneously. D. not enough information given to decide
Q.2 Mavis has a light clock with her on a train. The train is moving with respect to Stanley. Observing Mavis light clock, Stanley concluded that it is running A. Fast B. Slow C. At the same rate
Q.3 According to Stanley, Mavis clock is running slow. To verify this, Stanley places two of his clocks at two locations, one at the beginning of the light pulse, one at the end of the light pulse. The proper time refers to A. The time interval of these two events as measured by Mavis clock. B. The time interval of these two events as measured by Stanley s two clocks at two locations. C. A time interval measured by a clock in the inverted Lorentz frame.
Q.4 According to Stanley, Mavis clock is running slow. A. Mavis agrees with Stanley that her clock is slow. B. Mavis disagrees with Stanley and claims that Stanley s two clocks at two locations are not synchronized correctly. C. Mavis agrees with Stanley that the length of her spaceship is Lorentz contracted.
