Question

What is the wavelength and frequency of radar waves? and does it have any dangers?

thanks :)

Answer 1

radar is microwave radiation. In fact that is how microwave ovens were invented. In other words if you stand in front of a big radiating radar, you get microwaved.
For example
IEEE Radar Band Designations
Frequency Wavelength IEEE Radar Band designation
1 - 2 GHz 30 - 15 cm L Band
2 - 4 GHz 15 - 7.5 cm S Band
4 - 8 GHz 7.5 - 3.75 cm C Band
8 - 12 GHz 3.75 - 2.50 cm X Band
12 - 18 GHz 2.5 - 1.67 cm Ku Band
18 - 27 GHz 1.67 - 1.11 cm K Band
27 - 40 GHz 11.1 - 7.5 mm Ka Band
40 - 75 GHz V Band
75 - 110 GHz W Band
110 - 300 GHz mm Band
300 - 3000 GHz u mm Band
