depending of factors such as magnitude and direction. Unbalanced forces will cause changes in the direction or speed of an object. Electromagnetism is composed of magnetic fields and electric currents. The electromagnetic spectrum is mediated by a particle called photon. Example: heat‚ visible light‚ radio waves‚ X-rays‚ UV radiation.

describe the spectrum in the Terahertz range (1 THz = 1012). [1] The terahertz region of the spectrum lies on the border of where electronics and optics meet between the mm-wave and infrared bands (100 GHz-10 THz). THz wave could handle ultra broad band signals ‚ have very large absorption due to water or water vapours and are transparent through many materials (e.g. plastics ‚ papers‚ cloth and oil) that are opaque in visible and IR light. Many materials have a so called fingerprint spectrum in the

Throughout life‚ many people will encounter the saying “Communication is key” but may never identify the underlying message behind the phrase. When interpreted‚ this cliché supports the common goal in which every person subconsciously shares: to communicate and interact with others. Humans are biologically wired to participate in this exchange and communication can arguably be considered one of the ultimate purposes people serve. Ironically enough‚ the instinct to communicate is a daily aspect
