A wave transmits information or energy from one point to another in the form of signals, but no material object makes this journey. The frequency of a wave is obtained by including a factor of time in the mix. We are completely dependent on waves for all of our wireless communications.
A wave is a flow or transfer of energy in the form of oscillation through a medium – space or mass. Sea waves or tides, a sound we hear, a photon of light travelling, and even the movement of small plants blown by the wind are all examples of different waves. A simple wave illustration is as follows.
Types of Waves in Physics
Different types of waves have different sets of characteristics. Based on the orientation of particle motion and direction of energy, there are three categories:
- Mechanical waves
- Electromagnetic waves
- Matter waves
