Understanding Wave Basics
Before diving into the specifics of the PhET waves simulation, it’s essential to grasp the foundational concepts of waves. Waves are disturbances that transfer energy from one point to another without the physical transport of matter. They can be categorized into several types:
Types of Waves
1. Mechanical Waves: These require a medium to travel through, such as sound waves or water waves.
2. Electromagnetic Waves: These do not require a medium and can travel through a vacuum, such as light waves and radio waves.
3. Matter Waves: These are associated with particles and describe quantum mechanical phenomena.
Key Characteristics of Waves
- Wavelength: The distance between successive crests or troughs of a wave.
- Frequency: The number of waves that pass a fixed point in a unit of time, usually measured in Hertz (Hz).
- Amplitude: The height of the wave from the rest position to the crest or trough, indicating the energy of the wave.
- Speed: The rate at which the wave travels through the medium, which is determined by both the frequency and wavelength.
