Which of the following statements is CORRECT? Question options:

A. Sounds that differ in frequency differ in amplitude.

B. Sounds that differ in loudness are said to differ in quality.

C. The speed of sound in air at 20ºC is 330 m/s .

D. Sound does not require a medium in order to travel through

E. Sound waves are an example of longitudinal waves.

E.) Sound Waves are an example of longitudinal waves.

Explanation:

I was sure either A or E was correct so I had to look it up. In reference to three sources, it is proven that sound waves are longitudinal. Therefore, without a doubt, I would try to go with E. I know D is wrong as well as B most definitely. That is because sound always requires a medium to travel through in order to be heard; additionally sounds don't necessarily have to be a certain rate of loudness in order to be considered of different quality. Therefore leaving you with A, C, or E. Additionally C is a false fact as well. So I highly suggest choosing E because there is sufficient sources to prove that. I'll provide a direct link down below.
