Gordon wrote this passage about mechanical waves for his physics class. But he got most of his facts mixed up. Only one sentence

is correct. Which sentence is it?
A) Mechanical waves don’t need a medium to travel. When they travel through a vacuum, mechanical waves are oval-shaped. They’re either transverse or double transverse waves.

B) Mechanical waves can apply pressure to and push on objects in their path.

C) But they travel slower in denser mediums.

Answer: The correct answer is "Mechanical waves can apply pressure to and push on objects in their path".

Explanation:

Mechanical wave is wave in which there is an oscillation of the wave. The energy is transferred through a medium. Mechanical waves can apply pressure to and push on their path. Only the energy is transferred not the matter.

Mechanical waves are of three types: Transverse wave, Longitudinal wave and Surface wave. The examples of the mechanical wave are sound wave and water wave.

Sound is a pressure disturbance which travels through a medium. It consists of compression and rarefaction.

The mechanical waves need a medium for their propagation. They travel faster in denser medium.

Therefore, the correct option is (B).
