Question

A proggesive wave of frequency 500 hz travelling with a speed of 350 m/s a compressional max. Appears at a place at a given instant .The min. time interval after which of rarefraction max. occurs at the same time

Answer 1

Here they have given time period, so after every time period there will be compression at the same place but at half the time period there will be a rarefaction.i have attached a solution

Answer 2

Answer:

1/1000 seconds

Explanation:

This question has a confusing language. Read it 2-3 times.

It means that currently the compression point is at a place. The question says when will it get replaced by the refraction point. In order to reach the place where the compression point is right now, the refraction point has to cover a whole wavelength. So now after simplifying the question it means that when will the wave cover a whole wavelength. It now quite easy to solve..
