Question

Which has a higher frequency, a wave that makes 7 cycles per second or one that makes 12 cycles per second?

Answer 1

Answer:

A sound wave that has a higher frequency is a wave that makes 12 cycles per second.

Explanation:

The frequency of a wave is the same as the frequency of the vibrations that caused the wave. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
