Question

Please check my answer!! I would be great if you could explain this to me a little as well...

To find the amplitude, measure_____

a. the horizontal distance between consecutive positions
b. the horizontal distance between a consecutive crest and trough
c. vertical distance from crest to trough
b. vertical distance from a crest to a rest position**

I think its the last one but this question is a little confusing.

Answer 1

D. you are correct.

Answer 2

agree

y = A sin (2 pi f t)
so A is half the distance from sin = -1 to sin = +1
or from sin = 0 to sin = 1

Answer 3

[AI-generated answer — Explain Bot]

To find the amplitude, you need to measure the vertical distance from a crest to the rest position. The rest position is the equilibrium point of the wave, which is the position of the medium in the absence of a disturbance. The crest is the highest point of the wave, while the trough is the lowest point. The amplitude represents the maximum displacement of the medium from its rest position. Therefore, the correct answer would be "d. vertical distance from a crest to a rest position."
