The main properties of a wave are amplitude, wavelength, period, frequency and speed. Amplitude is the height of the wave which is measured in meters. Wavelength is the distance between crests measured in meters. Period is the time it takes for one complete wave to pass a given point and it is measured in seconds. Frequency is  the number of complete waves that pass a point in one second, measured in inverse seconds, or Hertz (Hz). The speed of the wave is the horizontal speed of a point on a wave as it propagates, measured in meters / second. Waves also have crests and troughs. A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to.

Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us.  Electromagnetic waves are waves that can travel to through the vacuum of outer space. A mechanical was is a wave that is an oscillation of matter, and therefore transfers energy through a medium. Mechanical waves unlike electromagnetic waves, require the presence of a material medium in order to transfer their energy from one location to another.
