Solution


Q.

Interference pattern can be observed due to superposition of the following waves:

A.   y=asinωt

B.   y=asin2ωt

C.   y=asin(ωt-ϕ)

D.   y=asin3ωt

Choose the correct answer from the options given below:                           [2024]
1 B and C  
2 B and D  
3 A and C  
4 A and B  

Ans.

(3)

For obtaining interference pattern, the two superimposing waves should be of same frequency. It is clear from the given options that waves in option A and C have same frequency, so they will superimpose and give interference pattern.
