PS.9 a-b - Wave Characteristics

The student will investigate and understand the characteristics of transverse waves. Key concepts include

a) wavelength, frequency, speed, amplitude, crest, and trough; and

b) the wave behavior of light.

  • The wavelength and frequency of a light wave gives its observable color.

  • I can explain how waves vary.
  • I can explain how mirrors in stores trick me.


  • Visible light is a form of radiant energy that moves in transverse waves.
  • All transverse waves exhibit certain characteristics: wavelength, crest, trough, frequency, and amplitude. As wavelength increases, frequency decreases. There is an inverse relationship between frequency and wavelength.


In order to meet this standard, it is expected that students will

a) model a transverse wave and draw and label the basic components. Explain wavelength, amplitude, frequency, crest, and trough.

b) describe the wave behavior of visible light (refraction, reflection, diffraction, and interference).

     design an investigation to illustrate the behavior of visible light – reflection and refraction. Describe how reflection and refraction occur.
