Two waves each of intensity `I_(0)` are disturbing the same medium. Find resultant intensities at the point where the phase difference `phi` is (1) `2pi`
(ii) `pi`
(iii) `(pi)/(2)`
`(2pi)/(3)`

Text Solution

Verified by Experts

(i) `I = I_(0) + I_(0) + 2sqrt(I_(0) xxI_(0)) = 4I_(0)`
(ii) `I = I_(0) + I_(0) - 2sqrt(I_(0) xx I_(0)) = 0`
(iii) `I = I_(0) + I_(0) + 2sqrt(I_(0)I_(0) xx 0 = 2I_(0)`
(iv) `I = I_(0) + I_(0) + 2sqrt(I_(0) xx I_(0)) xx (- (1)/(2)) = I_(0)`
