In fog, photographs of the objects taken with infrared radiations are more clear than those obtained during visible light because
Options
- AI- R radiation has lesser wavelength than visible radiation
- Bscattering of I-R light is more than visible light
- Cthe intensity of I-R light from the object is less
- Dscattering of I-R light is less than visible light
Correct answer
D. scattering of I-R light is less than visible light
Step-by-step solution
In fog, visible light is scattered more according to Rayleigh scattering, but scattering of infrared radiations is less due to high wavelengths, hence in fog, photographs of the objects taken with infrared radiations are more clear.
