What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves. It is transmitted through air, water, or solids and can be heard when it reaches a person's or animal's ear.

What are examples of light energy?

Back

Examples of light energy include sunlight, artificial light from bulbs, and laser beams. Light energy is electromagnetic radiation that can be seen by the human eye.

What is heat energy?

Back

Heat energy, also known as thermal energy, is the energy that comes from the temperature of matter. It is the energy that is transferred from one body to another due to a temperature difference.

What is the difference between sound energy and light energy?

Back

Sound energy is mechanical energy that travels through a medium (like air or water) as waves, while light energy is electromagnetic energy that can travel through a vacuum and does not require a medium.

Front

What is an example of something that is not sound energy?

Back

An example of something that is not sound energy is a light bulb emitting light. Light energy is not produced by sound waves.
