Here's why:
* Disturbance: A wave is caused by a disturbance, meaning a change in the medium. This could be a vibration, a push, or a pull.
* Medium: The medium is the substance the wave travels through (liquid, solid, or gas).
* Movement: The disturbance propagates through the medium, transferring energy without transporting matter.
Types of Waves:
* Mechanical Waves: These waves require a medium to travel. Examples: sound waves, water waves, seismic waves.
* Electromagnetic Waves: These waves can travel through a vacuum (like space) and don't need a medium. Examples: light waves, radio waves, X-rays.
Key Characteristics of Waves:
* Amplitude: The maximum displacement of the medium from its rest position.
* Wavelength: The distance between two consecutive crests or troughs.
* Frequency: The number of waves passing a point per second.
* Speed: The rate at which the wave travels.
