Question

If at a place the speed of a sound wave of frequency $300Hz$ is $V$, the speed of another wave of frequency $150Hz$ at the same place will be:

• A. $V$
• B. $V/2$
• C. $2V$
• D. $4V$

Answer 1

The correct option is A $V$

Velocity of sound wave remains same at the same location because it depends on the conditions like temperature , etc.

V= const = $\lambda f$

Thus, the $\lambda$ increases when f increases.
