Question

Which describes the relationship between the frequency wavelength, and speed of a wave as the wave travels through

different media?
As speed changes, wavelength changes and frequency remains constant.
o As speed changes, frequency changes and wavelength remains constan
O As speed changes, wavelength and frequency change.
As speed changes, wavelength and frequency remain constant.

Answer 1

As speed changes, wavelength and frequency change.

Step-by-step explanation:

-Wave speed is related to both the wavelength and wave frequency as:

`Speed= Wavelength * Frequency`

-Wavelength is measured in meters, frequency in Hertz(Hz) and speed in m/s.

-Increasing the wavelength of a wave decreases its frequency and therefore the wave speed will remain constant .

-As a such, the product of wavelength and wave frequency is still the same speed.
