Answer:
infrared radiation
Step-by-step explanation:
The spectral band of ultraviolet is = 10 nm to 400 nm
The spectral band of radio waves is = 1mm - 100 km
The spectral band of visible light is = 400 nm - 700 nm
The spectral band of infrared is = 700 nm to 1 mm.
The peak intensity of radiation from Mars is 14,000 nm. It lies in the infrared spectral band. It has long wavelength and small frequency.
