Answer:
These wavelengths are longer than wavelength of visible light.
These wavelengths form the infra-red part of the spectrum.
Explanation:
- Solar spectrum lies in three parts of the electromagnetic spectrum, that is; Ultraviolet, visible and infra-red.
- Visible light lies from 400 nm to 700 nm.
- Ultraviolet region precedes visible spectrum and has shorter wavelength than it. Beyond visible spectrum, infrared part of the spectrum starts and has longer wavelength than it.
- The wavelength of sunlight that are greater than 700 nm wavelength have longer wavelength than visible light and lie in the infra-red part of the spectrum.
