Question

Dawn and Aram have stretched a slinky between them and begin experimenting with waves. As the frequency of the waves is doubled the wavelength is______.

Answer 1

halved

Step-by-step explanation:

The velocity of the a wave is obtained by multiplying the frequency and wavelength.

`v=f\lambda\\\Rightarrow f=(v)/(\lambda)\\\Rightarrow \lambda=(v)/(f)`

Where

v = Velocity

f = Frequency

`\lambda` = Wavelength

The velocity here is constant. So, if the frequency is doubled the wavelength is halved.
