Light Production Methods Quiz

What is the primary cause of light emission in incandescence?

• Chemical reaction

• Absorption of light

• Mechanical action

• Heating of a substance

How does fluorescence differ from phosphorescence?

• Fluorescence involves a delay in light emission

• Phosphorescence does not involve electron movement

• Phosphorescence occurs immediately after light absorption

• Fluorescence emits light immediately after absorption

Which of the following is an example of triboluminescence?

• A firefly lighting up

• A bulb lighting up

• A glow stick glowing

• Rocks emitting light when rubbed

What happens inside a glow stick to produce light?

• Light is absorbed and re-emitted

• Mechanical action causes light emission

• A chemical reaction occurs between mixed chemicals

• Electrons move to a higher energy level

Bioluminescence is a type of light production that occurs in:

• Chemical laboratories

• Mechanical devices

• Living organisms

• Non-living substances
