Which amongst the given radiation is preferred for taking photographs in fog?
A. Ordinary visible light
Infrared radiation has the maximum wavelength and minimum frequency.
Energy is directly proportional to frequency; hence energy associated with them is also low.
Thus the infrared radiation gets least scattered by the tiny particles in the fog.
That is why infrared wave is preferred over all others which have a higher frequency and gets scattered hence can’t be focused.
