Study Notes
Light Refraction and Reflection
- Refraction: Refers to the bending of light as it passes from one medium to another, due to a change in speed.
- Snell's Law: Governs refraction and relates the angles of incidence and refraction to the indices of refraction of the two media.
Reflection of Light
- Law of Reflection: States that the angle of incidence equals the angle of reflection when light reflects off a smooth surface.
Refraction Properties
- Speed of Light: Light slows down as it transitions from air (approximately 299,792 km/s) to glass (approximately 200,000 km/s).
- True Statements about Refraction: These include that light bends toward the normal when entering a denser medium and away from the normal when entering a less dense medium.
Total Internal Reflection
- Total Internal Reflection: Occurs when light travels from a denser medium to a less dense medium, and the angle of incidence exceeds the critical angle, resulting in all light being reflected back into the denser medium.
