Question

state the factors on which echo depends​

Answer 1

Answer:

When a sound wave is reflected by some object then it is again heard by us this reflected sound is called echo. Velocity of sound waves depends on the temprature, pressure, humidity. In solids it also depends on Youngs Modulus, in liquids on bulk Modulus, in gases sound propagates adiabatically.

Answer 2

Answer:

When a sound wave is reflected by some object then it is again heard by us this reflected sound is called echo. Velocity of sound waves depends on the temprature, pressure, humidity. In solids it also depends on Youngs Modulus, in liquids on bulk Modulus, in gases sound propagates adiabatically.

Explanation:

Two main factors affect the speed of sound: the material that makes up the medium—such as air or water—and the temperature. If we know the medium and the temperature, however, we can predict the speed of sound.
