A radio station's channel, such as 100.7 FM or 92.3 FM, is actually its frequency in megahertz ( MHz M H z ), where 1MHz=106Hz 1 M H z = 10 6 H z and 1Hz=1s−1 1 H z = 1 s − 1 . Calculate the broadcast wavelength of the radio station 100.7 FM. Express your answer to four significant figures and include the appropriate units.
