The separation between a node and the next antinode in a vibrating air column is 25 cm. If the speed of sound in air is `340 m s^-1`, find the frequency of vibration of the air column.

Text Solution

Verified by Experts

The correct Answer is:

C, D

Distance betweenn two nodes or antinodes `rarr lamda/4=25cm`
`rarr lamda=100cm=1m`
`rarr n=v/lamda=340Hz`
