Question

When a stationary wave is formed then its frequency is

• A. same as that of the individual waves
• B. twice that of the individual waves
• C. half that of the individual waves
• D. $\sqrt{2}$ that of the individual waves

Answer 1

Answer: (A)

same as that of the individual waves

Answer 2

If $y_{\text {Incident }}=a \sin (\omega-k x)$ and $y_{\text {stationary }}=a \sin (\omega t) \cos k x$ then it is crease that frequency of both is same $(\omega)$.
