de Broglie hypothesis
Matter particles have a wave-like nature characterised by the de Broglie wavelength.
de Broglie wavelength
The wavelength of a matter particle = h/p, where p is the momentum of the particle.
Process in which an atom loses energy by photon emission, as a result of an electron inside an atom moving from an outer shell to an inner shell.
Mass per unit volume.
Spreading of waves on passing through a gap or near an edge.
A plate with many closely-ruled parallel slits on it.
Splitting a beam of white light by a glass prism into colours.
Distance in a given direction.
The force of fluid resistance on an object moving through the fluid.
Stretches easily without breaking.
The ratio of useful energy transferred (or the useful work done) by a machine or device to the energy supplied to it.
The force applied to a machine to make it move.
Point beyond which a wire is permantely stretched.
Property of a solid that enables it to regain its shape after it has been deformed or distorted.
Process of electrical conduction in a solution or molten compound: due to ions moving to the oppositely charged electrode.
