Waves

Waves

1. Types

   • Transversal: Moves from left to right at exactly 90% degrees
   • Longitudinal: Vibrate parallel to the direction the waves travel.
   • Electromagnetic: Produced by the vibration of charged particles
   • Mechanic: Any wave that is an oscillation of matter that transfers energy through a medium.
   • Pulse: A wave with only a shape that moves sideways.
   • Periodic: A wave with continuous repetition of patterns which help determine the wavelength and frequency.

2. Components

   • Wave lenght: The lenght of a wave from left to right
   • Frequency: The number of waves emitted per second.
   • Amplitude: Measure of how tall the waves are above the rest position.
   • Peak: The top
   • Through: The bottom
   • Equillibrium line: Horozontal line which is in the middle of the wave.

3. Formulas

   • Wave speed is equal to frequency times the wave lenght.
   • Total energy is half spring constant times amplitude squared

4. Wave interference

   • Destructive: Overlapping waves produce a new wave, with a smaller amplitude than the sum of the inidvu=idual waves combined.
   • Constructive: It's when overlapping waves produce another wave whose amplitude is the sum of the individual waves combined.
