Ray Optics The wave model of Light has one serious drawback, though: Unlike other wave phenomena such as Sound, or surface waves, it wasn‟t clear what the medium was that supported light waves. Giving it a name – the “luminiferous aether” – didn‟t help. James Clerk Maxwell‟s (1831 – 1879) theory of electromagnetism, however, showed … Read more

Waves A wave can be described as a disturbance that travels through a medium from one location to another location.It is a disturbance or variation that transfers energy progressively from point to point. It may take the form of an elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature. When … Read more
