5 beats/second are heard when a turning fork is sounded with a sonometer wire under tension, when the length of the sonometer wire is either 0.95 m or 1 m. The frequency of the fork will be :
View answer and explanation
Correct option: A
195 Hz
Option A (195 Hz) is correct because the frequency of the fork is calculated using the beat frequency and the relationship between frequency and length of the sonometer wire.
