Question

Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.

Which statement accurately describes something that Yolanda can do as a part of her study?

She can use destructive interference to generate a wave with an amplitude of 3.1 m.
She can use constructive interference to generate a wave with an amplitude of 1.5 m.
She can use destructive interference to generate a wave with an amplitude of 2.8 m.
She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Answer 1

d) She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Answer 2

Answer: She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Step-by-step explanation:

It is given that, Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.

We know that the intensity of a wave is directly proportional to the square of the amplitude.

The amplitude of the resultant wave in constructive interference increases while in case of destructive interference the amplitude decreases.

So, the correct statement that Yolanda can do as a part of her study is (D).
