Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Calculate Brewster’s angle first before making assumptions on polarization.
Question 2
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.
💡 Hint: Use the Brewster's angle formula and consider the concept of polarization.
