Document Summary
Like sound, light is also a wave. Unlike sound, light requires no medium through which to travel. Light is an electromagnetic wave (em wave) An em wave is produces when an electrical charge is accelerated. All objects both emit and receive energy from surrounding objects in the form of em c = 3. 0 x 10 m/s m/s (speed of light) radiation. An em wave arises from closely coupled oscillations of the electrical mield and the magnetic mield. The em wave is a transverse wave. Part of electromagnetic (em) spectrum (small part) White light is a mixture of all colours. All em waves travel at a well demined speed c = 3. 0 x 3 x 10 m/s in a vacuum. Classically, light is treated as a travelling wave radiating uniformly from a source in all directions. We treat light as a ray when discussing its optical properties.
