Question

If two identical waves interfere at a point in the same medium, then the resultant wave has the same _________ as of the interfering waves.

• A. angular frequency
• B. wave number
• C. Both options $\left(A\right)$ and $\left(B\right)$
• D. None of these

Answer 1

The correct option is C Both options $\left(A\right)$ and $\left(B\right)$

Two identical waves interfere at a point in the same medium to give a resultant wave of the same angular frequency and wave number as of the interfering waves.

Hence, option $\left(C\right)$ is the correct answer.
