5.3.5 Light and the Atmosphere

Double check that your light source is set to laser and is emitting ultraviolet (UV) light. Drag the sulfuric acid droplet out into spot 1.

How does the light interact with the sulfuric acid droplet?

• Transmits

• Reflects

• Absorbs

Continuing with sulfuric acid: turn on 'show energy' -- what does the energy do when it interacts with the sulfuric acid?

• Transmits

• Reflects

• Absorbs

Continue with sulfuric acid droplet: does UV light cause a change to the sulfuric acid droplet?

• Yes

• No

Double check that your light source is set to laser and is emitting ultraviolet (UV) light. Drag carbon dioxide out into spot 1 (this will remove sulfuric acid)

How does the UV light interact with the carbon dioxide?

• Transmits

• Reflects

• Absorbs

Continuing with carbon dioxide: turn on 'show energy' -- what does the energy do when it interacts with the carbon dioxide?

• Transmits

• Reflects

• Absorbs

Continue with carbon dioxide: does UV light cause a change to the carbon dioxide?

• Yes

• No

Double check that your light source is set to laser and is emitting ultraviolet (UV) light. Drag ozone out into spot 1 (this will remove carbon dioxide)

How does the UV light interact with the ozone?

• Transmits

• Reflects

• Absorbs

Continuing with ozone: turn on 'show energy' -- what does the energy do when it interacts with the ozone?

• Transmits

• Reflects

• Absorbs

Continue with ozone: does UV light cause a change to the ozone?

• Yes

• No

Which materials in the atmosphere stop the progress of UV light towards Earth?

• Sulfuric acid droplet (reflects)

• Carbon dioxide (transmits)

• Ozone (absorbs)
