Police often monitor traffic with "K-band" radar guns, which operate in the microwave region at 22.235 GHz (1 GHz = 109 Hz). Find the wavelength (in nm and Å) of this radiation. Enter your answers in scientific notation.

The wavelength is and of this radiation

Explanation:

To calculate the wavelength of light, we use the equation:

where,

= wavelength of the light  = ?

c = speed of light =

= frequency of light =

Thus wavelength is and of this radiation
