A radio station broadcasts at a rate of 89.3 million cyces each second.
what is the period of this wave? (frequency = 89.3 MHz)
if the wavelength is 3.359 meters, what is the speed of this radio wave?
If the speed of light is 3x10^8 m/s, what would be the wavelength of the light created by the laser (in a bar code scanner) that resonates at a frequency of 462,000 GHz?
