As sound travels through an absorbing medium 1.its amplitude decreases
2)it gains velocity and power
3)its power decreases
4)its direction is altered
5)it loses intensity

Question

Quizplus · Accepted Answer

Option 1 is correct as sound energy is absorbed by the medium and hence its amplitude decreases. 
Option 3 is correct as some sound energy is lost as heat due to friction and other factors, leading to a decrease in its power. 
Option 5 is correct as sound energy is dissipated over a larger area as it travels through the medium, resulting in a decrease in its intensity. Option 2 and 4 are incorrect as the velocity and direction of sound waves remain unchanged in an absorbing medium.
