What is reflection?

• Reflection is the refraction of light through a medium.

• Reflection is the change in direction of a wavefront at an interface between two different media.

• Reflection is the emission of light from a source.

• Reflection is the absorption of light by an object.

Explain the law of reflection.

• The law of reflection states that the angle of incidence is equal to the angle of reflection when a ray of light hits a surface.

• The law of reflection states that the angle of reflection is perpendicular to the surface.

• The law of reflection states that the angle of incidence is greater than the angle of reflection.

• The law of reflection states that light bends when it hits a surface.

Give an example of regular reflection.

• Seeing your reflection in a mirror

• Seeing your reflection in a dream

• Seeing your reflection in a pond

• Seeing your reflection in a shadow

What is refraction?

• Refraction is the emission of light.

• Refraction is the bending of light.

• Refraction is the reflection of light.

• Refraction is the absorption of light.

Describe how light bends when it passes from air into water.

• Light bends towards the normal when it passes from air into water.

• Light bends perpendicular to the surface when it passes from air into water.

• Light bends away from the normal when it passes from air into water.

• Light does not bend when it passes from air into water.

Explain why a straw appears bent when placed in a glass of water.

• The straw appears bent due to gravitational pull.

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

• The straw appears bent as a result of magnetic forces.

• The straw appears bent in water due to refraction of light.

What are prisms used for?

• Prisms are used for magnifying sound.

• Prisms are used for cooking food.

• Prisms are used for refracting or reflecting light.

• Prisms are used for flying in the sky.

How does a prism separate white light into its component colors?

• Reflection causes white light to separate into its component colors.

• Refraction at different angles based on wavelength causes white light to separate into its component colors.

• Diffraction of light waves within the prism results in color separation.

• Absorption of certain colors by the prism leads to color separation.

What is the color spectrum?

• The color spectrum is the range of colors that can be smelled

• The color spectrum is the range of colors that can be seen when white light is dispersed through a prism.

• The color spectrum is the range of colors that can be tasted

• The color spectrum is the range of colors that can be heard
