Light and Sound
Sound is caused by
Vibrations
Box A temperature: 18C
Box B temperature: 25C
This box has more thermal energy
Box B
The movement of charged particles is
Electrical Energy
This has chemical energy stored
Food, batteries and fuel
Eating and then going for a run
Chemical energy to kinetic energy
Longitudinal waves move
in the direction of motion
Thermal energy moves from
Hot to cold
The symbol for a light bulb is
A circle with an X inside
Light travels in
Rays
Playing the drums
Kinetic energy to sound energy
The part of the electromagnetic spectrum we can see
visible light
The car is hot after being parked in the sun all day
Radiation
When the switch is closed the lightbulb is
shining
Electrical energy is transformed into these types of energy when you plug your laptop and switch it on
Sound, Light, thermal
Photovoltaic cells
Light energy to electrical energy
This medium is where sound travels the fastest
Solids
Boiling water
Convection
This material is an electrical conductor
Metals
The thermal energy transfer a toaster uses
Radiation
Switching a flashlight on
Chemical energy to electrical energy to light energy
Name one part of the electromagnetic spectrum other than visible light
Radio waves, microwaves, infrared, ultraviolet, x-ray, gamma ray
This thermal energy transfer happens in liquids and gases only
Convection
A break in the circuit will cause the light bulb to
not light up
Energy transfer is
When the same type of energy moves from one place to another
Fireworks
Chemical energy to thermal energy, light energy and sound energy
