Light,heat and sound are all energy.
Five examples of energy transformation:television-electrical energy->light energy->sound energy->heat energycar-chemical energy->mechanical energy->sound energy->heat energylight bulb-electrical energy->light energy->heat energyrubber duck-kinetic energy->elastic energy->sound energymatch-chemical energy->light energy->heat energy
sound wave
heat energy, electricity energy, light energy and sound energy
When a TV turns on, electrical energy is converted into light (in the form of the screen's display) and sound energy (from the speakers). Some energy is also dissipated as heat due to the TV's components.
Electrical energy--->sound energy+ heat energy and light energy Cheers M
Light is in fact a form of energy along with sound and heat.
sound energy???
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
In a campfire, chemical energy stored in the wood is converted into heat and light energy through the process of combustion. The heat produced from the fire can be used for warmth or cooking, while the light energy is visible as the flames.
Heat is a type of energy. Thus heat is energy, but there are other forms that energy can take (such as sound, chemical, light, etc).
light, sound and some heat energy
All energy converters will give out heat. Tv's will get energy from their source and convert it to sound, light and heat energy.
