What is a longitudinal wave ?
The longitudinal waves travel in a coiled spring at a rate of 4 m/s. The distance between two consecutive compressions is 20 cm. Find :
(i) Wavelength of the wave (ii) Frequency of the wave
Define the term wave velocity. Write its S.I. unit.
The speed of light in air is :
A cannon is fired at A (see diagram). An observer at B hears two sounds. The first sound is heard after 1 second and the second 3s after the observer sees the flash. (Velocity of sound = 340 ms−1)
(i) Why does the observer see the flash before he hears the sound?
(ii) Calculate the distance x between the observer and the wall.
Explain the types of mechanical waves.
Give scientific reasons.
In earlier times, people used to listen for the arrival of a distant train by putting their ear to the rail.
