Questions & Step-by-Step Solutions
What is the angle of incidence at which light is completely polarized upon reflection?
Correct Answer: Brewster's angle
Step 1: Understand that when light hits a surface, it can be reflected or refracted.
Step 2: Know that polarization is when light waves vibrate in a specific direction.
Step 3: Learn about Brewster's angle, which is the angle at which light is completely polarized upon reflection.
Step 4: The formula for Brewster's angle (θ_B) is tan(θ_B) = n2/n1, where n2 is the refractive index of the second medium and n1 is the refractive index of the first medium.
Step 5: To find Brewster's angle, you need to know the refractive indices of the two materials involved.
Step 6: Calculate Brewster's angle using the formula by dividing n2 by n1 and then taking the arctangent (inverse tangent) of that value.
