Question

The speed of sound in a medium does not change with the change of

• A. frequency
• B. wave length
• C. pressure
• D. density

Answer 1

Answer: (A)

frequency

With change in frequency, the wavelength of particle changes which makes it have constant velocity.

As velocity $v=\frac{\lambda }{T}$ $=\sqrt{\frac{\gamma P}{s}}$

Velocity depends on wavelength, pressure and density.
