Vedclass · Answer

(D) According to Rayleigh scattering, the intensity of scattered light is inversely proportional to the fourth power of its wavelength $(I \propto 1/\lambda^4)$.Since infrared radiations have a longer wavelength compared to visible light, they undergo significantly less scattering by the particles in fog.Because of this reduced scattering, infrared radiations can penetrate through fog more effectively than visible light.Therefore, photographs taken with infrared radiations in foggy conditions are much clearer than those taken with visible light.

In fog, photographs of the objects taken with infrared radiations are more clear than those obtained during visible light because
