Question

If the velocity of a sound wave remains constant and its frequency increases, which characteristics of the wave will decrease?

A. energy

B. speed

C. amplitude

D. wavelength

Answer 1

the answer to this question is the letter C

Step-by-step explanation:

Answer 2

Option C is correct

Step-by-step explanation:

Wavelength of the sound waves varies inversely with respect to frequency which means that if frequency increases wavelength will decrease and if frequency decreases wavelength increase.

Mathematically this relation can be represented as -

`W \alpha (1)/(f)`

Where W represents the wavelength and f represents the frequency

When frequency is constant, wavelength exhibit direct proportionality relationship with speed.
