Frequency is measured in hertz. Which option best describes hertz?

the length of a wave over a specified length of time

the number of waves that pass a certain point within a certain time

the distance that one cycle of a wave will travel

the number of vibrations produced per minute

Answer 1

"the number of waves that pass a certain point within a certain time"

Step-by-step explanation:

Hertz is a unit used to measure frequency. The best option that describes hertz is "the number of waves that pass a certain point within a certain time". One hertz is equal to one cycle per second, which means that if a wave has a frequency of 10 hertz, it completes 10 cycles per second. Therefore, hertz measures how often a wave oscillates or completes a cycle per second.
