Waves are movements that carry energy from one place to another.
Mechanical Waves: These waves need something to travel through, like a solid, liquid, or gas. Some examples are sound waves and water waves.
Electromagnetic Waves: Unlike mechanical waves, these don’t need anything to travel through. They can even move through empty space! Common examples are light waves and radio waves.
The energy that a wave carries depends on how big the wave is, which is called its amplitude. If you double the size of the wave, the energy it carries actually increases by four times!
In air, sound waves move at about 343 meters per second. On the other hand, electromagnetic waves can travel much faster, at around 300 million meters per second in empty space.
