A state trooper’s car sends out a radar signal at a frequency of 14 GHz.
Find the wavelength of this signal. The wave speed is 2.998 × 108 m/s.
Answer in units of m

speed= frequency*wavelength.
wavelength = speed / frequency
F = 14 GHz = 14*10^9 Hz = 14*10^9 cycles/second.
Wavelength = V/F = V * 1/F = 2.998*10^8 / 14*10^9 = meters.
Wavelength = V/F = V * 1/F = 2.998*10^8 / 14*10^9 = meters.
