Question

Which of the following is a constant for sound in a
given medium?
(1) Frequency (2) Wavelength
(3) Speed (4) Amplitude

Answer 1

Frequency
Because frequency depends upon the source & not in the medium it is travelling..
Hope u get it...

Answer 2

Answer:

1 : Frequency

Explanation:

We analyze the given properties of sound as follows :

1) Amplitude

The amplitude of the sound wave decreases as the wave moves away from the sources. This is because the energy of the sound wave spreads over a large area.

2) Velocity

The velocity of sound wave varies depending on the medium. Sound moves at different velocities in different medium.

3) Wavelength

The wavelength of sound wave changes as sound wave moves from one medium to another.

4) Frequency

The frequency of sound wave remains constant from the source even as sound moves from one medium to another.

From the explanation above the correct answer is 1.
