A spacecraft moves past a student with a relative velocity of 0.90c. If the pilot of the spacecraft observes 10 min to elapse on his watch, how much time has elapsed according to the student’s watch?
Answer to relevant QuestionsSome stars appear reddish, and others appear blue. Which of these two types of stars have the higher surface temperature? Explain. Make a graph showing how the wavelength of the most intense radiation component of blackbody radiation varies with the body’s absolute temperature. By what ratio does λmax change (final/initial) if the body’s absolute ...Each photon in a beam of light has an energy of 6.50 x 10-19 J. What is the light’s wavelength? What type of light is this? Find the approximate temperature of a red star that emits light with a wavelength of maximum emission of 700 nm (deep red). What is half the maximum wavelength shift for Compton scattering from a free electron?
