Refraction

Why does the part of the pencil that's underwater look bent?

• Because the pencil actually bends in water

• Because of the refraction of light

• Because of the reflection of light

• Because the water distorts the shape of the pencil

What does the word 'normal' refer to in the context of light experiments?

• An ordinary ray of light

• A ray of light that does not bend

• The most common outcome in an experiment

• A line at a right angle to a surface

What is the angle of incidence?

• The angle between the emergent ray and the surface

• The angle between the incident ray and the normal

• The angle between the refracted ray and the normal

• The angle between the incident ray and the surface
