Question

Students create a standing wave

with three loops on a slinky 3.75 m
long. They time 20 oscillations in
6.73 s. What is the wavelength of
the standing wave?
(Unit = m)​

Answer 1

Step-by-step explanation:

Given that,

Number of loops are 3

Length of slinky is 3.75 m

They time 20 oscillations in 6.73 s.

We need to find the wavelength of the standing wave.

For 3 loops,
`L=(3\lambda)/(2)`

Here,
`\lambda` is the wavelength of the standing wave

So,

`\lambda=(2L)/(3)\\\\\lambda=(2* 3.75)/(3)\\\\\lambda=2.5\ m`

So, the wavelength of the standing wave is 2.5 m.
