Suppose frequency of emitted photon is fo when electron of a stationary hydrogen atom jumps from a higher state m to a lower state n If the atom is moving with a velocity v c and emits a photon of frequency f during the same transition then which of the following statements is not possible 1 f may be equal to fo 2 f may be greater than fo 3 f may be less than fo 4 f cannot be equal to f
