medium
Definition
In science, a medium is a substance that can transmit energy. Examples of media include air, water, and glass.
Energy can be transmitted through a medium in different ways. For example, sound waves can travel through air, and light waves can travel through air and glass.
The speed of energy transmission through a medium depends on the properties of the medium. For example, sound waves travel faster through the air than through water.
Media are important because they allow us to communicate and interact with the world around us. We can hear sounds because they travel through the air to our ears. We can see light because it travels through the air to our eyes.
How can the word be used?
