← ScienceWhich consequence results when laser light encounters mist at night?
A)Constructive interference increases beam intensity.
B)Beam dispersion decreases retinal hazard.✓
C)Rayleigh scattering depolarizes the reflected fraction.
D)Fresnel diffraction eliminates chromatic abberation.
💡 Explanation
Beam dispersion reduces power per unit area, thus minimizing retinal hazard because power is spread over many particles due to Rayleigh scattering dominating, therefore the dispersion reduces hazard from specular reflection, rather than interference which would increase intensity.
