Name one solid, on liquid and one gas through which sound can travel.
A body vibrating with a time-period of `1/256` s produces a sound wave which travels in air with a velocity of 350 m/s. Calculate the wavelength.
The velocities of sound waves in four media P, Q, R and S are 18,000 km/h, 900 km/h, 0 km/h and 1200 km/h respectively. Which medium could be a liquid substance?
Give scientific reasons:
As the sound wave propagates from one place to the other in air, the air itself is not required to move from one place to the other.
State three characteristics of the medium required for propagation of sound?
State two properties of medium on which the speed of sound in it depends.
Compare approximately the speed of sound in air, water and steel.
Answer the following question :
How does the speed of sound differ in different media?
Assuming the speed of sound in air equal to 340 m/s and in water equal to 1360 m/s, find the time taken to travel a distance 1700 m by sound in (i) air (ii) water.
