Answer #1

Frequency = speed of light divided by wavelength

As speed of light is constant, frequency and wavelength of radiation are inversely related.

Higher frequency radiation will have lower wavelength.

Lower frequency radiation will have higher wavelength.

Given frequency of microwave radiation = 1 × 109 Hz

Frequency of radar beam = 5 × 1011 Hz

Lower is frequency of microwave radiation, so its wavelength is higher.

Frequency of X rays = 1017 - 1020 Hz

This is close to radar beams.
