Light Concepts

What is reflection of light?

• Reflection of light is the process where light bounces off a surface.

• Reflection of light is the absorption of light by a surface.

• Reflection of light is the emission of light from a source.

• Reflection of light is the bending of light as it passes through a medium.

Define refraction of light.

• Refraction of light is the change in direction of light as it passes from one medium to another, caused by the change in its speed.

• Refraction of light is the absorption of light by a medium

• Refraction of light is the emission of light from a source

• Refraction of light is the reflection of light off a surface

Explain absorption of light.

• Absorption of light is the process where light energy is converted into sound.

• Absorption of light is the process where light energy is taken in by an object, causing its atoms or molecules to move to a higher energy state.

• Absorption of light is the process where light energy is released by an object.

• Absorption of light is the process where light energy is reflected by an object.

How are shadows formed?

• Shadows are formed when an object blocks light.

• Shadows are formed by dancing unicorns

• Shadows are formed by invisible fairies

• Shadows are formed by magical spells

What causes different colors in light?

• Variations in the wavelength of light

• Reflection off of surfaces

• Changes in air pressure

• Temperature fluctuations

What are the types of lenses?

• Convex lenses and concave lenses

• Transparent lenses and opaque lenses

• Flat lenses and bumpy lenses

• Short lenses and tall lenses

What is light?

• Light is a form of sound waves.

• Light is a type of solid matter.

• Light is a chemical reaction.

• Light is electromagnetic radiation that is visible to the human eye.

How does a mirror reflect light?

• By bending light

• By emitting light

• By absorbing light

• By obeying the law of reflection

What is the law of reflection?

• Angle of incidence is equal to angle of reflection

• Angle of reflection is greater than angle of incidence

• The law of reflection only applies to concave mirrors

• Angle of incidence is perpendicular to the reflecting surface

What is the difference between reflection and refraction?

• Reflection is the bouncing back of light, while refraction is the bending of light.

• Reflection is the scattering of light, while refraction is the diffraction of light.

• Reflection is the absorption of light, while refraction is the emission of light.

• Reflection is the bending of light, while refraction is the bouncing back of light.
