Homework Statement


Your favorite radio FM radio station broadcasts at a carrier frequency of 94.7 Megahertz.

What is the wavelength of the carrier frequency radio signal?


Homework Equations



velocity=wavelength(frequency)

The Attempt at a Solution



94.7x10^-6(w)= 3x10^8
w= 3.2 wavelength


I think this is right just not 100% sure

Are you sure 94.7 Megahertz = 94.7 x 10-6 Hertz?

Apart from that typo it looks like you've done it ok. Remember your units though.

o ok i see what i did wrong its 94.7x10^6 hertz but the answer comes out to 3.167898627E12, it just seems weird. would that be right?
and what would the unit be?
 


You had the answer correct in the first place despite the typo. What is the SI unit of length?
 


o ok so it would be 3.2 meters?
