Question

A cello string is 0.695 m long, and transmits waves at 204 m/s. What frequency does it produce? (Unit = Hz)​

Answer 1

146.76 Hz

hope it helps you

Answer 2

The frequency produced is: F = 146.76 Hz

Explanation:

We are given:

Length of string = 0.695 m

Waves speed = 204 m/s

We need to find Frequency

The formula used is:
`F=(v)/(2L)`

where F is frequency, L is length of string and v is wave speed

We have :

L = length of string = 0.695

v= Wave speed = 204 m\s

Finding frequency by putting values in formula:

`F=(v)/(2L)\\F=(204)/(2(0.695))\\F=(204)/(1.39)\\F=146.76\:Hz`

So, The frequency produced is: F = 146.76 Hz
