Two waves from coherent sources meet at a point in a phase difference of 
. Both the waves have same intensities. Match the following two columns.
Column-I | Column-II | ||
(A) | If | (I) | Resultant intensity will become four times |
(B) | If | (II) | Resultant intensity will become two times |
(C) | If | (III) | Resultant intensity will remain unchanged |
(D) | If | (IV) | Resultant intensity will become three times |
Text Solution
Verified by ExpertsThe correct answer is:
A
Resultant intensity of two waves from coherent sources is given by
Here, 
So, 
If 
,
If 
,
If 
,
If 
,
Hence, A-(IV), B-(II), C-(I), D-(III).
