Question

What two units are used to measure the frequency and amplitude of a sound wave?

A. Hertz is a measure of frequency, and a decibel is a measure of amplitude.

B. A decibel is a measure of frequency, and hertz is a measure of amplitude.

C. The quantization is a measure of frequency, and sampling is a measure of amplitude.

D. Sampling is a measure of frequency, and the quantization is a measure of amplitude.

Answer 1

Answer:

A. Hertz ----f amplitude.

Explanation:

The rules of physics confirm that frequency is measured in HERTZ and the amplitude is measured in Decibel. And hence, the correct option here is certainly the first option as it states that the frequency is measured in HERTZ and the amplitude is measured in Decibel. Hence, the first one is the correct choice for this question.
