Acommunications satellite transmits a radio wave at a frequency of 9.4 x 10^9 hz. what is the signal’s wavelength? assume the wave travels in a vacuum. show your work.

To calculate this we will use the light equation:
λ

We have Frequency .
We know that speed of light in vacuum is .
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).

So:



λ
⇒ λ
⇒ λ
⇒ λ

Ithink your answer will be c hope that’s you
