Topic: Special Theory of Relativity Doppler Effect in Light Instruction: Do you agree to the following claims? Yes or No? Explain your reasoning for choosing either a yes or no response. 1) When the frequency of a galaxy is red-shifted it is moving away from us. 2) Both wavelengths of sound and light increase as the source moves closer to the observer. 3) The observed frequency in transverse Doppler Effect in light does not apply the relativistic factor. 4) The observed (or received) frequency of light is affected by only one factor, the speed of source or observer. 5) When the frequency is red-shifted it means that the frequency falls within the red range of the spectrum
