Now its just algebra. Khan Academy is a 501c3 nonprofit organization. Radio waves travel at the speed of light so in this case v is equal to 299792458 metres per second ms and 245 GHz is 2450000000 Hz so thats the frequency.
2998 x 108 ms 600 nm v.
Calculating frequency and wavelength from displacement graphs Our mission is to provide a free world-class education to anyone anywhere. The equation that relates the two is. Light in vacuum air 300000 kms. This is 245 gigahertz in most microwaves.
