Question

A guitar string vibrates back and forth 88 times in 1 minute. Round your answers to the following questions to the nearest tenth.

What is its frequency in hertz?

Answer 1

The frequency of the guitar string vibrates back and forth 88 times in 1 minute = 1.5 Hz

Explanation:

A hertz is used to measure one cycle (complete wave) of a vibration.

The number of cycles per second is the frequency, measured in hertz.

A guitar string vibrates back and forth 88 times in 1 minute

The vibrations in 1 second =
`(88)/(60)` = 1.466 Hz ≈1.5 Hz

The frequency of the guitar string vibrates back and forth 88 times in 1 minute = 1.5 Hz
