Question

@aaronq Two sinusoidal sound waves with slightly different frequencies combine to form a third sound wave called a beat. How does the amplitude of the beat change over time, or does it remain constant?

The amplitude increases and decreases in a sinusoidal pattern.
The amplitude changes in a pattern of a steady increase, then a sudden decrease.
The amplitude remains constant.
The amplitude increases indefinitely

Answer 1

Answer 2

I think it remains constant

Answer 3

i think so too, why would they change if everything stays constant
