The Doppler effect is a change in the frequency of a wave which occurs if one is in a different frame of reference from the emitter of the wave. Relative to us, we observe such a change if an emitter of a wave is moving relative to us.

In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation http://engineeringphysics.weebly.com/uploads/8/2/4/3/8243106/srit__unit_i_laser.pdf WebMonochromatic light is coherent, if the waves of the monochromatic light oscillate in the same direction and have the same frequency and the same phase. In other words: the monochromatic light must be collimated. This requirements applies to a laser as Nuclear Ghost mentioned it.

"WebInterference and Superposition. When two waves meet they will interfere and superpose. After they have passed they return to their original forms. This is true if they are coherent or not. At the point they meet, the two waves will combine to give a resultant wave whose amplitude (or intensity) may be greater or less than the original two waves.

This definition of coherence allows the decomposition into contributions corresponding to the non-classical correlations between the subsystems and localized on each subsystem.

WebIncoherent sources do not. If two sources are coherent, we must add the amplitudes of the individual waves and then square them to get the resulting intensity. If they are incoherent, we just add intensities. In the following section, we derive formulas for the resulting sound level for both cases. First we consider incoherent addition, then ...
