3 cards from this section. Quick, good the night before a test.
What happens to light at Brewster's angle?
Think about how light can behave differently based on angles.
What is the formula for Brewster's angle?
Recall that it involves the refractive indices of the media.
What angle results in light being completely polarized upon reflection?
Think about the specific angle where polarization occurs in light.
True or False: The reflected ray at Brewster's angle is perpendicular to the refracted ray.
Recap the relationship between the two rays at this special angle.
You have a beam of light entering a medium with a refractive index of 1.6 from air. If the angle of incidence is 45 degrees, will the light be polarized as it reflects? If so, what is the Brewster's angle?
Calculate Brewster’s angle first before making assumptions on polarization.
Light travels from water (n=1.33) into glass (n=1.5). Calculate the Brewster's angle and explain the implications for light's polarization.
Use the Brewster's angle formula and consider the concept of polarization.
