Question 302: Waves

Question

Which of the following statements is NOT true?

Accepted Answer

The statement that is NOT true is:
$$	extbf{Option C: Sound can travel through vacuum.}$$
Here's why:
Sound is a mechanical wave, which means it needs a medium (like air, water, or a solid) to propagate.
In a vacuum, there is no medium to carry the sound, so sound cannot travel in a vacuum.
Therefore, Option C contradicts the basic concept of how sound waves work.
All the other statements are true:
Option A: Sound generally travels in a straight line until it is redirected by obstacles.
Option B: Sound is indeed propagated as waves.
Option D: Sound is a form of energy.
