what is the frequency of radio wave radiation that has a wavelength of 390 m
+36919 Use f = c/w where f= frequency c = speed of light (3 x 10^8 m/s) w = wavelength
f = (3 x 10^8 m/s) / 390 m I think you can 'punch it out' from there.......right?
The answer will be in /s or Hz (hertz...cycles per second)
