Challenge Problems
Push your limits with advanced challenges
Illustrate the path of light while moving from water (n=1.33) to air (n=1), and determine the critical angle for this scenario.
💡 Hint: Apply Snell's Law correctly for the transition between the two media.
Analyze a scenario where light travels from diamond (n ≈ 2.42) to air (n=1). Calculate the critical angle and discuss the implications for sparkling diamonds.
💡 Hint: Link the critical angle with how materials like diamond are cut for minimum light escape.
