A longitudinal wave has 20 compression and 20 rarefactions in 0.1 s. find its frequency
Answers
Answer:
refer to the attachment
Answer:
The frequency will be 100 Hz.
Given:
Number of compressions in a wave = 20
Number of refractions in a wave = 20
Time span = 0.1 seconds
As we know,
In a wave, if the density becomes low, it is refraction; if the density is high, then it is said to be compression.
The refraction in the wave is that part of the wave in which the medium of the particle s stretched apart and are the regions of low pressure.
The compression in the wave is the part of the wave in which the medium of the particles are compressed or brought together and are the regions of high pressure.
1 wave will be formed by 1 compression and 1 refraction.
In this question, we have 20 compressions and refractions
20 waves will be formed in 0.20 seconds
In 1 second frequency will be,
20/0.2 = 100 Hz
Therefore, the frequency in this wave will be 100 Hz.
