A strong sound signal is sent from a ship towards the bottom of the sea. It is received back after 1s. What is the depth of sea given that the speed of sound in water 1450 ms–1?
Assertion: The speed of sound in air is less than the speed of sound in solid.
Reason: If we increase the temperature of medium, the speed of sound increases in any medium.
Numerical problems:
Two persons are at opposite ends of a steel rod. One strikes the end of the rod with a stone. Find the ratio of time taken by the sound wave in the air and in steel to reach the second person. (Sound of speed in steel = 5960 ms-1, Sound of speed in air = 344 ms-1).
Numerical problems:
A Sound wave travels at a speed of 344 ms-1. If the wavelength is 1.5 cm, what is the frequency of the Wave? Will it be audible?
