What you’ll learn

  1. Reading a Wave DiagramIdentify wavelength and amplitude on a wave diagram.Use the axes, repeating points, and equilibrium line to read spatial repetition and displacement.
  2. Interpreting Wave MotionRelate frequency, period, speed, wavelength, phase, and wave type.Count cycles, apply the wave equations, compare cycle positions, and classify disturbance direction.

Questions this course answers

What is frequency?

Frequency counts cycles per second and is measured in hertz.

What is amplitude?

Amplitude is measured from equilibrium to a maximum displacement.

Which relation connects wave speed, frequency, and wavelength?

One wavelength passes in one period, so v = lambda/T = f lambda.
