← ScienceWhich mechanism limits visibility when hot exhaust enters atmospheric air?
A)Light scattering by diffraction
B)Light attenuation by absorption
C)Refraction creates mirage effects
D)Ray interference creates opacity✓
💡 Explanation
Ray interference occurs when the rapidly mixing hot and cold air cause variations in refractive index, therefore creating opacity because constructive + destructive interference patterns scatter incoming light non uniformly; scattering results rather than simpler atmospheric absorption.
