Explain the Wave Particle Duality
Any object in the world can be considered to be a particle or wave and will exhibit properties of both. For example, a photon of light, an electron, and a moving baseball all have wave- and particle-like properties. Any object has an associated deBroglie wavelength, suggested by a young Ph.D. candidate, Louis deBroglie, in 1924. The deBroglie wavelength is given by
λ = h /mv where λ is the deBroglie wavelength in m, h is Planck's constant ( h = 6.626 x 10 -34 Js), m is mass of the object in kg, and v is its speed in m/s. We have dealt a bit with the wave nature of light in the last few chapters. As a particle, light comes only in discrete packages called photons. For a given frequency of light you cannot have less than one photon of energy.
E = h f or E = h (c/ λ) where E is the energy of a photon in joules, h is Planck's constant ( h = 6.626 x 10 -34 Js), f is the light's frequency in sec-1, c is the speed of light 2.99 x 108 m/s and λ is the wavelength in meters.
Gauss' law for magnetic fields The magnetic flux by a closed surface is zero; no magnetic charges present. In differential form, div B = 0.
