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

Answer 1

Answer:

a) Not Accurate

b) Not Accurate

c) Accurate

d) Accurate

Explanation:

Part a

Not Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m

Part b

Not Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m

Part c

Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m by varying the phase difference between two waves she can achieve the desired results.

Part d  

Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m by varying the phase difference between two waves she can achieve the desired results.
