Which of the following statements is false?
o

o
b. when a sound wave reflects, some of the initial energy is lost.
o
c. an echo is a sound wave reflection.
o
d. reflection is when a sound wave bounces off an object.

It is false that sound waves are the only waves that reflect.

Option A

Explanation:

Reflection of the waves means that it is a process when waves hit any object, they bounce off from that object. Sound waves are not the only waves which reflect. Other waves which reflect are infrared waves and the radio waves.

Light waves might move through the material which is known as the process of refraction or might even bounce off the material, hence the light waves may or may not reflect. Thus there are other waves also which reflect from the objects.
