Answer :
[tex]\lambda = \frac{c}{f}[/tex]
λ - wavelength, c - the speed of light, f - frequency
[tex]f=200 \ kHz= 200 000 \ Hz \\ \\ \lambda=\frac{300 000 \ [\frac{km}{s}]}{200 000 \ [Hz]}=\frac{3}{2}=1.5 \ [km][/tex]
The wavelength of these waves is 1.5 km.

The wavelength of these waves is 1.5 km.
For any wave, Wavelength = (speed) / (frequency)
For radio waves, Speed = about 3x10⁸ meters per sec ("speed of light")
So Wavelength = (3 x 10⁸ m/s) / (200 x 10³ /sec) = 1,500 meters
For radio waves, Speed = about 3x10⁸ meters per sec ("speed of light")
So Wavelength = (3 x 10⁸ m/s) / (200 x 10³ /sec) = 1,500 meters
