Synopsis

Photoelectric effect – Light waves and photons – Einstein’s photo– electric equation – laws of photo – electric emission – particle natureof energy – photoelectric equation – work function – photo cells andtheir application.Matter waves – wave mechanical concept of the atom – wavenature of particles – De–Broglie relation – De–Broglie wave length ofan electron – electron microscope.Concept of space, mass, time – Frame of references. Specialtheory of relativity – Relativity of length, time and mass with velocity– (E = mc2).The true nature of light is difficult to assess. Experiments showed thatlight exhibited wavelike properties of diffraction and interference. On theother hand, photoelectric effect indicates that light has the aspects of aparticle photon, with both energy and momentum. Thus light exhibits awave-particle duality.The wave-particle duality was extended to particles as matter waves byLouis de Broglie. His theoretical study on the nature of particles andwaves led to the invention of a new mechanics of particles calledquantum mechanics.
