Reflection and Refraction

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light rays when they strike a surface. It occurs at the boundary between two different media.

Front

What is refraction?

Back

Refraction is the bending of light rays as they pass from one medium to another due to a change in speed.

What are the primary colors of light?

Back

The primary colors of light are Red, Green, and Blue.

Front

What are the secondary colors of light?

Back

The secondary colors of light are Yellow, Magenta, and Cyan.

What happens to light when it strikes a mirror?

Back

When light strikes a mirror, it is reflected according to the law of reflection, which states that the angle of incidence equals the angle of reflection.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light attempts to move from a denser medium to a less dense medium and the angle of incidence exceeds the critical angle.

Front

What is the critical angle?

Back

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

Front

How do prisms affect light?

Back

Prisms refract light, separating it into its constituent colors due to different wavelengths bending at different angles.
