Questions and Answers

Define a wave.

A wave is a disturbance that carries energy from one location to another without a net movement of particles.

What is the highest point of a wave called?

  • Wavelength
  • Amplitude
  • Crest (correct)
  • Trough

What does the term 'wavelength' refer to in a wave?

  • The height of the wave from the rest position
  • The number of waves passing a point per second
  • The distance between two consecutive crests (correct)
  • The time it takes for one complete wave cycle

Study Notes

Waves

  • Wave - a disturbance that carries energy from one place to another without moving the particles themselves.

Parts of a Wave

  • Crest - the highest point of a wave
  • Trough - the lowest point of a wave
  • Period - the distance between a crest and a trough
  • Wavelength - the distance between two consecutive crests or troughs
  • Frequency - the number of waves that pass a given point in a set amount of time
  • Amplitude - the distance between the rest position and the top of the wave

Two Types of Waves

  • Mechanical waves - waves that travel through a medium
    • Longitudinal waves - particle movement is parallel to the direction of wave motion. (Think of a slinky)
    • Transverse waves - particle movement is perpendicular to the direction of wave motion. (Think of a wave on a rope)
