Heat and Light Energy Quiz

Heat Energy

• Heat energy izes from the movement of particles within a substance.
• Faster particle movement equates to more heat energy.

Conduction

• Heat moves through direct contact between materials.
• Example: A metal spoon heating up in hot soup.

Convection

• Heat moves through the movement of fluids or gases.
• Example: Warm air rising and cool air sinking in a room.

Radiation

• Heat moves through electromagnetic waves, not needing a medium.
• Example: Heat from the Sun reaching Earth.

Light Energy

• Light is a form of electromagnetic radiation visible to the human eye.
• Light has particles called photons that travel in waves.

Transmission

• Transmission describes how much light and sound waves can pass through something.

Reflection

• Reflection is when waves (light or sound) bounce off surfaces.

Refraction

• Refraction is when waves (light or sound) change direction when passing between different mediums, changing speed.

Absorption

• Absorption is when energy from light or sound is taken in by a substance, often becoming heat.

Diffusion

• Diffusion is the scattering or spreading of energy (light or sound) as it moves through a medium or after interacting with a surface.
