Waves

1. Components of a wave

   • Peak/Crest
     • The highest point in a wave
   • Trought
     • The lowest point in a wave
   • Wavelenght
     • Distance between corresponding points of two consecutive
   • Amplitude
     • The maximum displacement/distance moved by a point on a vibrating body
   • Frequency
     • The number of waves that pass by each second
   • Equilibrium line
     • condition of a system when neither its state of motion nor its internal energy state tends to change with time

2. Types of waves

   • Mechanical
     • Oscillation of matter, therefore, transfers energy through a medium
       • Examples
         • Sound waves
           • Water waves
             • Seismic waves
         • Type
           • Microwaves
             • X-ray
               • Radio waves
                 • Ultraviolet waves
   • Electromagnetic
     • Waves that are created as a result of vibration between an electric field and a magnetic
     • Examples
       • Radio waves
         • Gamma rays
           • Infrared
             • Visible light
               • Ultraviolet
   • Pulse
     • A wave is a sudden distortion or disturbance that travels through a material or medium
     • Examples
       • Sound waves
         • Water waves
       • Type
         • Transverse wave
           • Compression
             • Wave packet
               • Shock wave
   • Periodic
     • A wave that repeats continuos pattern
       • Examples
         • Sound waves
           • Water waves
         • Properties
           • Amplitude
             • Wavelength
               • Frequency
                 • Period
                   • Velocity
   • Transversal
     • A moving wave whose oscillation is perpendicular to the direct of the waves propagation
     • Example
       • Vibration in a guitar string
       • Types
         • Light waves
           • Electromagnetic waves
             • Radio waves
   • Longitudinal
     • A wave whose displacement of the medium the same/opposite direct of the waves propagation
     • Examples
       • speaking on a microphone
         • Clapping
           • Vibration on a drunhead
       • Types
         • Sound waves
           • Ultrasound waves
             • Seismic p-waves

3. Waves interference

   • Constructive
     • When 2 small waves combined to form 1 bigger wave
       • Destructive
         • When 2 small waves combine to make the wave disappear

4. Energy wave formula

   • Formula
     • Wave speed formula
       • Purpose
         • It is use to find how much the wave travel in a certian amount of time
