B) (i) and (iv)
C) (iii) and (iv)
D) not possible at all
Correct Answer: D
Solution :
Interference is the superposition of two or more waves resulting in a new wave pattern. The terms refers to the interference of waves which are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. But two independent wave sources do not show interference. Hence, interference is not possible with the given independent waves.You need to login to perform this action.
