Question

Radio waves transmitted through space at 3.00 ✕ 108 m/s by the Voyager spacecraft have a wavelength of 0.137 m. What is their frequency (in Hz)?

Answer 1

Frequency,
`f=2.18* 10^9\ Hz`

Step-by-step explanation:

We have,

Speed of radio waves is
`3* 10^8\ m/s`

Wavelength of radio waves is
`\lambda=0.137\ m`

It is required to find the frequency of the radio waves. The speed of a wave is given by :

`v=f\lambda\\\\f=(v)/(\lambda)\\\\f=(3* 10^8)/(0.137)\\\\f=2.18* 10^9\ Hz`

So, the frequency of the radio wave is
`2.18* 10^9\ Hz`.
