Question

What happens when the amplitude of the grade of the sine function increases?

(Don’t pay attention to the answer chosen)

Answer 1

The increase of amplitude would increase distance between the maximum and minimun point of the wave.

Explanation:

We can defined the amplitude of a wave as the height of it, because it's the distance from the maxium point to the minimum point. In other words, it's the longest vertical displacement along the wave.

Additionally, amplitude represents power, when we apply waves to real phenomenons like the sound. So, greater grade of amplitude would represent louder sounds.

Therefore, the increase of amplitude would increase distance between the maximum and minimun point of the wave.
