Wavelength has units of meters (m), not m/s. Using λ = 200 m and c = 3.0×10^8 m/s,
f = c / λ = (3.0×10^8 m/s) / (200 m) = 1.5×10^6 Hz = 1.5 MHz = 1500 kHz.
So the radio station would need a frequency of 1.5 MHz.
f = c / λ = (3.0×10^8 m/s) / (200 m) = 1.5×10^6 Hz = 1.5 MHz = 1500 kHz.
So the radio station would need a frequency of 1.5 MHz.
