Reflection vs Refraction

Understanding Light Reflection and Refraction

This section delves into the fundamental concepts of light reflection and refraction, exploring how light interacts with different mediums.

Light Reflection

• Specular reflection occurs on smooth surfaces where the angle of reflection equals the angle of incidence.

• Natural surfaces exhibit diffuse reflection, causing parallel incident rays to reflect in various directions.

Light Refraction

• Refraction occurs when light changes direction as it moves from one medium to another.

• Snell's Law governs refraction, with the angle depending on the incidence angle and refractive indices of the media involved.

Applications of Light Refraction

This segment explores practical applications of light refraction in everyday scenarios and technological innovations.

Practical Examples

• Placing a pencil in water showcases refraction at the water's surface.
