The blue light from the sky has been polarized by:
A)selective absorption.
B)reflection.
C)double refraction.
D)scattering.

Question

Quizplus · Accepted Answer

The blue light from the sky is polarized primarily due to scattering. When sunlight enters the Earth's atmosphere, it collides with molecules and small particles, which scatter the light in all directions. This phenomenon, known as Rayleigh scattering, is more effective at shorter wavelengths, such as blue light, leading to the sky's blue color. The scattering process also polarizes the light.
