This study guide covers the concept of refraction, which is how light bends when it changes speed moving between different materials. It explores how the index of refraction (n) quantifies this bending and how Snell's Law predicts the angle of refraction. Finally, it explains total internal reflection and the critical angle, along with practice questions and exam tips covering these core concepts.

Because its speed changes
Because the amplitude of light increases
Because its wavelength increases
