Simplify each trigonometric expression. Physics When a ray of light passes from one medium into a second, the angle of incidence θ₁ and the angle of refraction θ₂ are related by Snell's law:
n₁sin θ₁=n₂sin θ₂ , where n₁ is the index of refraction of the first medium and n₂is the index of refraction of the second medium. How are θ₁ and θ₂ related if n₂>n₁ ? If n₂
