The frequency of radio waves of a radar on the Muscat highway is 145 MHz. The minimum size of the car (wavelength) that can be
detected by these waves:
O a. 145 x 10^6 m
O b. 2.0689 m
O c. 2.4 m
O d. 0.062 m
Suppose a radio wave has a wavelength of 2.00 meters. What it the frequency of the
radiation? It may be helpful to recall that v = AF for electromagnetic waves, while
v = c = 3.00 × 108 m/s.
