Exploring the Wonders of Light

What is reflection in terms of light?

• Reflection is the scattering of light in different directions.

• Reflection in terms of light is the bouncing back of light waves when they hit a surface.

• Reflection is the conversion of light into heat energy.

• Reflection is the absorption of light by a surface.

How does light behave when it hits a mirror?

• Light passes through a mirror without any change.

• Light is absorbed completely by the mirror.

• Light bends and changes direction when hitting a mirror.

• Light reflects off a mirror according to the law of reflection.

What is refraction?

• Refraction is the bending of light as it passes from one medium to another.

• Refraction is the scattering of light in different directions.

• Refraction is the absorption of light in a medium.

• Refraction is the reflection of light off a surface.

Can you name a common example of refraction?

• A mirror reflecting light.

• A straw in a glass of water.

• A pencil lying on a table.

• A rainbow in the sky.

What happens to light when it passes through water?

• Light reflects off the surface of water without entering it.

• Light is absorbed completely by water without any bending.

• Light bends and slows down when it passes through water.

• Light speeds up and changes color when it passes through water.

Why does a straw look bent in a glass of water?

• The straw appears bent because it is made of flexible material.

• The water in the glass is causing the straw to warp.

• The straw looks bent due to the color of the water.

• A straw looks bent in a glass of water due to the refraction of light.

What is the angle of incidence?

• The angle of incidence is the angle between the incoming ray and the normal to the surface.

• The angle of incidence is the angle between two incoming rays.

• The angle of incidence is the angle between the outgoing ray and the surface.

• The angle of incidence is the angle formed by the surface and the ground.

What is the angle of reflection?

• The angle of reflection is always 90 degrees.

• The angle of reflection is half of the angle of incidence.

• The angle of reflection varies with the surface texture.

• The angle of reflection is equal to the angle of incidence.

How do prisms affect light?

• Prisms only reflect light without changing it.

• Prisms create light without any external source.

• Prisms refract and disperse light into a spectrum of colors.

• Prisms absorb all light without any effect.

What is total internal reflection?

• Total internal reflection can happen at any angle of incidence.

• Total internal reflection occurs only in solids.

• Total internal reflection is the absorption of light at a boundary.

• Total internal reflection is the complete reflection of a wave at the boundary of two media when the angle of incidence exceeds the critical angle.
