Study Notes
Snell's Law and Refraction
- Snell's Law: n₁ sin θ₁ = n₂ sin θ₂
- n₁: refractive index of medium 1
- n₂: refractive index of medium 2
- θ₁: angle of incidence
- θ₂: angle of refraction
Critical Angle
- Critical Angle (θc): The angle of incidence that produces an angle of refraction of 90 degrees.
- Beyond this angle, total internal reflection occurs.
- n₁ sin θc = n₂ sin 90°
Angle of Deviation (A)
- In a prism, the angle between the incident ray and emergent ray is the angle of deviation (A)
- A = θ₁ + θ₂ - A
- θ₁ = angle of incidence
- θ₂ = angle of emergence
- A= angle of the prism
Relationship between angles
- θ₁ = Angle of incidence
- θ₂ = Angle of refraction
- α=Φ₁ - A (where Φ₁ = angle of incidence and A = angle of prism)
- Φ₂ = θ₂ - A (where θ₂ = Angle of refraction and A = angle of prism)
Refractive Index (n)
- n = sinθ₁/ sinθ₂
- n is a constant related to the speed of light in different media, and θ₁ and θ₂ are the angles of incident light and transmitted light.
- n represents the ratio between the speed of light in a vacuum and the speed of light in the medium.
