Challenge Problems
Push your limits with challenges.
Question 1
If light traveling from glass (n=1.5) to air (n=1) hits the interface at 60 degrees, calculate both the reflectance and the transmittance.
💡 Hint: Use Snell's Law to find the refracted angle.
Question 2
Consider a light beam polarized perpendicular to the plane of incidence striking a boundary at Brewster's angle. What can you determine about the reflectance?
💡 Hint: Brewster’s angle involves using the refractive indices of the two media.
