00:05Question says, what is the phase difference between two successive crests in the wave?
00:15A pi, B pi upon 2, C 2 pi, D 4 pi.
00:24Is, we have to find phase difference. So, to calculate phase difference delta phi,
00:32we will use the formula delta phi is equal to 2 pi upon lambda into delta x means path difference.
00:45As delta x means path difference is equal to lambda. Take a suppose, this is a transverse wave.
00:59So, this is crest, this is trough and this is crest. So, the distance between two successive crests
01:07is equal to wavelength means lambda. So, here delta x is equal to lambda.
01:19So, phase difference delta phi will be equal to 2 pi upon lambda into delta x which is given as
01:30lambda.
01:32So, lambda will be get cancelled with lambda. So, phase difference delta phi will be equal to 2 pi.
01:42So, the correct option will be C 2 pi.
01:45So, the correct option will be C 2 pi.
01:47Do this as without the borrowings?
01:48Here, there it is.
01:48So, let's see.
01:49Again, what else do you say?
