Aradio station's channel, such as 100.7 fm or 92.3 fm, is actually its frequency in megahertz (mhz), where 1mhz=106hz. calculate the broadcast wavelength of the radio station 104.9 fm.

When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s. 

3 x10^8 m/s = wavelength/104.9 x 10^6 Hz   (Hertz is 1/s)
wavelength = 2.86 meters

Ithink it’s 98 because jajajjajansmsmjs
