Study Notes
Light Reflection
- Light reflects off a surface when it strikes it, bouncing back into the medium from which it came.
- The angle of incidence (incoming light) is equal to the angle of reflection (outgoing light).
Light Refraction
- Refraction is the process where light bends as it enters a different medium, such as from air to water.
- This phenomenon occurs due to changes in the speed of light in different materials.
Factors Influencing Refraction
- The angle at which light is refracted is determined by the indices of refraction of the two media involved.
- Snell's law is used to calculate this relationship, correlating the angles of incidence and refraction.
Law of Reflection
- The law of reflection describes how the angle of incidence equals the angle of reflection for a given surface.
- It establishes a fundamental relationship in optics, where reflective surfaces mirror incoming light.
Light Transitioning from Air to Water
- When light moves from air into water, it slows down and bends towards the normal (an imaginary line perpendicular to the surface).
- This bending results in the apparent distortion of objects submerged in water compared to their appearance in air.
