What occurs during absorption in the context of light?

• Energy is created by particles of matter

• Energy carried by light is reflected by particles of matter

• Energy carried by light is transferred to particles of matter

• Energy carried by light is destroyed

Why does a flashlight become dim in the distance?

• Because the light particles move faster

• Because the air particles reflect all the light

• Because the air particles absorb some of the energy from the light

• Because the flashlight runs out of power

What is refraction?

• The reflection of a wave off a surface

• The bending of a wave as it passes at an angle from one medium to another

• The absorption of a wave by a medium

• The transmission of a wave through a medium without bending

Why does refraction occur?

• Because the wave gets absorbed by the medium

• Because the frequency of light changes as it passes through different mediums

• Because the speed of light changes as it passes through different mediums

• Because the wave reflects off the surface of the medium
