Question

Consider a radioactive nucleus that is travelling at a speed with respect to the lab frame. It emits rays of frequency in its rest frame. There is a stationary detector (which is not on the path of the nucleus) in the lab. If a ray photon is emitted when the nucleus is closest to the detector, its observed frequency at the detector is: (December)
