Question

For a sound wave propagating in a medium, increasing its frequency will increase its ______.

विकल्प

• wavelength

• speed

• number of compressions per second

• time period

Answer 1

For a sound wave propagating in a medium, increasing its frequency will increase its number of compressions per second.

Explanation:

Frequency is the number of compressions/oscillations passing a point per second, so increasing frequency increases the number of compressions per second. Speed remains determined by the medium, and wavelength/time period do not increase.
