Sound Test - 27...

The sketches I to IV in Fig. show sound waves, all formed in the same time interval. Which diagram shows a bass (low frequency) note?

Different musical instruments sound different even when they play a note with the same pitch.

Sound waves requires a .......... to travel through.

A sound of wave produces $40$ crests and $40$ troughs in $0.4s$. What is the frequency of the wave?

A sound wave has a frequency of 192 Hz and travels the length of a football field, 91.4 m, in 0.27 s. What is the period of the wave?

The waves that transfer vibrations and disturbance are:

The relation between frequency(f) and time period(T) is given by

Echocardiography is used to diagnose heart diseases which utilises infrasonic waves.

Water waves in a shallow dish are $6 cm$ long. At one point, the water moves up and down at a rate of $4.8$ oscillations/s. What is the time period of the water waves?

In a ripple tank, 10 full ripples/s are produced. The distance between peaks of consecutive trough and crest is 15 cm. Calculate the frequency.
