Reflection & Refraction

Front

What is the phenomenon called when light changes direction as it passes from one medium to another?

Back

Refraction

Front

What do we call the bouncing back of light when it hits a surface?

Back

Reflection

Front

What is the term for the angle between the incident ray and the normal line at the point of incidence?

Back

Angle of incidence

Front

What is the term for the angle between the reflected ray and the normal line at the point of incidence?

Back

Angle of reflection

Front

What is a medium in the context of light?

Back

A material that light can travel through.

Front

What is the law that states the angle of incidence is equal to the angle of reflection?

Back

Law of Reflection

Front

What happens to light when it passes from air into water?

Back

It bends towards the normal due to refraction.

Front

What is total internal reflection?

Back

The phenomenon that occurs when light hits a boundary at an angle greater than the critical angle, causing it to be completely reflected back into the medium.

Front

What is the critical angle?

Back

The minimum angle of incidence at which total internal reflection occurs.

Front

What is dispersion in the context of light?

Back

The separation of light into its component colors due to different degrees of refraction.
