Question

Solar radiations reaching earth have a wavelength of

• A. 400-700 nm
• B. 300-740 nm
• C. 300-2600 nm
• D. 300-16000 nm

Answer 1

The correct option is C 300-2600 nm

The part of the spectrum that reaches Earth from the sun is between 100 nm and 1 mm. This band is broken into three ranges: ultraviolet, visible, and infrared radiation. Ultraviolet contains wavelengths between 100-400 nm.Visible light falls within the range of 400-700 nm, and infrared light contains wavelengths from 700 nm to over 1 mm. So the correct answer is ' 300 - 2600 nm'
