Background Information for Learners

Every day you come across diferent types of waves. The sound you hear when the school bell rings depends on sound waves. The rainbow you see after the ram depends on light waves. A tny wave can travel across the water in a glass, while a huge wave can travel across the ocean Sound waves, light waves, and water waves seem very different from one another. So what exactly is a wave?

A wave is a disturbance that caries energy from one place to another. Matter is NOT carried with the wave. A wave can move through matter (called a "medium"), but some waves do not need a medium to be able to move. If a wave needs a medium we call it a mechanmcal wave. If a wave can travel without a medium, (for example, through space), we call it an electromagnetic
wave. Ome good example of energy transier by waves s the wave caused by an earthquake. The ground shakes from side to side and up and down as the wave move through it The ground does not travel with the wave but it is the energy that travels in a wave
In the case of an earthquake the kinetic enerey fromn the movement of the ground is being transferred. The waves crashing in the shore trying to knock you down 1s another good example Ocean waves travel from the middle of the ocean to the shore, one after another

Now that you have basic understanding of how waves transfer energy, let us now move to the findamental indicators of the wave's energy:

1 Frequency - the number of waves passing a point in a certain time, measured in wave per second or Hertz (Hz); the higher the frequency, the closer the waves and the greater the energy


2.Amplitude - the distance fronm the center line or from rest position to crest (highest point) or trough (lowest point), the energy of the wave vaies directly to 1ts amplitude


3.Wavelength - the distance between two successive crests or troughs, measured in meters (m): a higher frequency causes a shorter wavelength and greater energy


4.Speed - the measure of the distance a wave travels in a certan amount of time, it is determined by the type of wave and the nature of the medium.
