Reflection and Refraction

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, due to a change in its speed.

How do lenses affect light?

Back

Lenses refract light, bending it to focus or disperse the light rays.

Front

What happens to light when it travels from air to water?

Back

Light bends towards the normal line, causing refraction.

What is the difference between reflection and refraction?

Back

Reflection involves light bouncing off a surface, while refraction involves light bending as it passes through different materials.

What does it mean for a material to absorb light?

Back

To absorb light means that the material takes in the light energy rather than reflecting or transmitting it.

What is the path of light in a uniform medium?

Back

In a uniform medium, light travels in a straight line.

Front

What is the normal line in the context of reflection and refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence.

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to reflect entirely back into the medium.

What is the critical angle?

Back

The critical angle is the angle of incidence above which total internal reflection occurs.
