Light Refraction Quiz

What causes the part of a pencil submerged in water to look bent?

• The pencil is actually bent

• The light waves are refracted as they pass through water

• The water distorts the shape of the pencil

• The light waves are reflected off the water surface

Why do light waves behave differently in different materials?

• Light waves have different colors in different materials

• Light waves travel faster in air than in water

• Different materials absorb light waves differently

• Different materials emit different types of light waves

What happens to the speed of light when it reaches a different material?

• The speed of light increases

• The speed of light decreases

• The speed of light remains the same

• The speed of light depends on the color of the light

What is the term used to describe the bending of light as it passes through different materials?

• Reflection

• Absorption

• Refraction

• Diffraction

What is the normal?

• A line at a right angle to a surface

• A line that represents the speed of light

• A line that connects the incident and emergent rays

• A line that represents the color of light

What is the angle of incidence?

• 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 emergent ray

• The angle between the refracted ray and the emergent ray

What is the angle of refraction?

• 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 emergent ray

• The angle between the refracted ray and the emergent ray

What happens to the light ray when it exits a plastic block?

• The light ray bends towards the normal

• The light ray bends away from the normal

• The light ray continues in a straight line

• The light ray splits into multiple rays

What type of lens is a convex lens?

• A lens that converges light rays

• A lens that diverges light rays

• A lens that absorbs light rays

• A lens that reflects light rays
