Sound Test - 40...

The equipment based on properties of sound used for medical purposes is based on:

When the string on a guitar is tightened, its pitch

Sonar is a device for:

Frequency of a sound wave if it travels with a speed of 330 ms$$^{-1}$$ in air and the wavelength of the wave is 330 cm is :

A longitudinal wave is travelling along a spiral spring with a velocity of $$2 \  m/s$$. If the period of the wave is $$0.2 \ s$$, find the wavelength.

The characteristics of sound which enables us to distinguish two musical sounds coming from different sources but having the same frequency and loudness is :

Transverse waves cannot travel through

A body shouts inside a deep well and hears the echo 0.4 s after shouting. if the speed of sound is 340 $$ms^{-1}$$ find the depth of the water level in the well :

What is the wavelength of a longitudinal wave if the distance between the 5th rarefaction and the 6th rarefaction is 25 cm?

A boy standing between two cliffs claps and hears 2 echoes after 2s and 2.5 s respectively. If the velocity of sound is 330 $$ms^{-1}$$, find the distance between he two cliffs :
