Waves Characteristics Review

Waves Characteristics Review

1. Components of a wave.

   • Peak/Crest
     • A pointed crest on the head distinguished from shell crest.
   • Trought
     • Is an elaborated region of relatively low atmosphere.
   • Wave/length
     • The distance between succesive crests of a wave.
   • Amplitude
     • The maximum extent of a vibration or osciliation.
   • Frequency
     • The rate at which something occurs or is a repeated a particular period of time.
   • Equilibrium Line
     • The line on a glacire that divides the zone of ablation from the accumulation zone.

2. Types of Waves.

   • Mechanical vs Electromagnetical.
     • Electromagnetic waves are that have no medium to travel whereas mechanical waves need a medium for its transmission.
   • Pulse vs Periodic.
     • Waves can be broadly separated into pulses and periodic waves. A pulse is a single disturbance while a periodic wave is a continially osciliating motion.
   • Transversal vs Longitudal.
     • In a transverse wave the particles are displaced perpendicular.

3. Wave Interference.

   • Constructive.
     • It occurs whenever waves come together so that they face with each other.
   • Destructive.
     • Occurs when waves come together in such a way that they competely cancel each other out.
   • Energy Wave Formula.
     • =1/2 uw^2 A^2 v
   • Wave Speed Formula.
     • v=fx2
