Light bounces when it hits a medium; e.g., mirror., The Angle of Incidence is equal to the Angle of Reflection., 𝜃𝑖 = 𝜃𝑟, Light stays in one medium., They both changes the directions and speed of light., Property of light., Can be described using Ray Optics., Light bends as it travels through two different mediums, e.g., air to water., The angle of Incidence is not equal to the Angle of Refraction., n1 sin ⁡𝜃1 = 𝑛2 sin 𝜃2, If n2 > n1, 𝑡ℎ𝑒𝑛 𝜃2 < 𝜃1, then light bends toward the normal line., If n2 < n1, 𝑡ℎ𝑒𝑛 𝜃2 > 𝜃1, then light bends away from the normal line..
