The frequency of natural vibrations of a body is determined by

The frequency of ultrasonic vibrations is

(A) : Resonance is a special case of forced vibration in which the natural frequency of vibrations of the body is the same as the impressed frequency and the amplitude forced vibration is maximum. (R) The amplitude of forced vibration of a body increases with an increase in the frequency of the externally impressed periodic force.

With what the natural frequency of oscillation of a body be dedermined

The frequency of a vibrating body is 10 Hz. The time taken by it to complete 5 vibrations is _____ s.

The frequency of a vibrating body situated in air……………
