Question

Using the information given in the preceding question, explain why sunsets are red.

Short answer

If we have various intensities measured from different angles, the refracted light will be polarized.

Step-by-step solution

Definition of wavelength

The wavelength is the length of a periodic wave's spatial period, or the distance across which the wave's structure repeats.

Step 2: Experiment to determine the polarization of the refracted light

Brewster's angle is the angle of incidence at which the reflected light is completely plane polarized.

The polarization of light can be determined by measuring the intensity of light refracting from various angles. If the intensity evaluated from different angles is uneven, the refracted light will be polarized.

In the plane parallel to the plane of incident light and in the direction perpendicular to the axis of motion, the refracted light should be partially polarized.

The refracted light will be polarized if different intensities are measured from different angles.
