Express your answer in terms of the wavelength CPreatice Hail, IncExplanation / Answer
II A. The freuqencies of the two sources is equal since, if we assume the wavefronts to be travelling at a constant speed through the same space, the distance between the crests and troughs (wavelengths) of both the sources is the same.
Yes, the two sources are in phase.
If we assume a bold line to be a crest and a dotted line to be a trough along the wavefront, then we see that both the sources are producing the crests and the troughs together.
Hence the two sources are said to be in phase.
