Waves

Waves

1. A wave is a disturbance involving the transfer of energy from a place to another.

   • The material waves travel trough is called medium
     • Waves that require a medium to travel are called mechanical waves
       • Mechanical waves form when a source of energy causes a medium to vribatre

2. Transversal waves

   • A wavethat vibrates the medium at right angles or perpendicular to the direction in wich the wave a travel is called a tranverse wave.
   • Waves are divided in diferent parts
     • Crest
       • The crest is the highest point of a wave
     • Trough
       • The lowest point of a wave

3. Longitudinal waves

   • Longitudinal waves vibrates the medium in the direction that waves travel
     • Compression
       • An area were the coils are close toghether.
     • Rarefaction
       • An area were the coils are spread out

4. Surface waves

   • Is the combination of longitudinal and transversal waves.
