Question

Students create a standing wave with three loops on a slinky 3.75 m longThey time 20 oscillations in 6.73 . What frequency would create a standing wave with 5 loops?

Answer 1

`f = 4.95\ hz`

Step-by-step explanation:

Given,

Student create wave of three loop on a slinky 3.75 m.

number of oscillations= 20

Time, t = 6.73 s

Frequency =
`(20)/(6.73)`

= 2.97 Hz

We need to find frequency when 5 loops is created.

`f = (5)/(3) * 2.97`

`f = 4.95\ hz`
