Question 10

A progressive wave of amplitude A A\,A has an intensity I0I_0I0​. This wave superposes with a second coherent wave of amplitude 1.3A at a detector. The phase difference between the two waves at the detector is π \pi\,π radians.

What is the resultant intensity of the superposed waves at the detector?

A

0.09I00.09 I_00.09I0​

B

0.69I00.69 I_00.69I0​

C

2.69I02.69 I_02.69I0​

D

5.29I05.29 I_05.29I0​
