00:04Question is, two sound waves having a phase difference of 60 degree have path difference
00:13of a to lambda, b lambda upon 2, c lambda upon 6, d lambda upon 3.
00:26In this condition we have to find path difference as we know that, to calculate phase difference
00:39we will use the formula delta phi is equal to 2 pi upon lambda into delta x.
00:51So, to find path difference means delta x, so this formula will become as, delta x will
01:01be equal to delta phi into lambda upon 2 pi as phase difference is given as 60 degree.
01:23So, 60 degree is equal to pi upon 3 radian. So, delta x will be equal to pi upon 3
01:43into lambda upon 2 pi.
01:49So, this is the value of delta phi. So, pi will be get cancelled with pi. So, delta x means
01:59path difference
02:00will be obtained as lambda upon 2, 3, d 6. So, path difference is obtained as lambda upon 6. So,
02:12the correct option will be c lambda upon 6.
02:17So, this is the value of delta x to 2, 3, d 6. So, the value of delta x is
02:18going to be
