Dispersion and Recombination of White Light * The angle between the two refracting faces of a prism is called the angle of the prism or refracting angle ‘A’. * The angle between the incident ray and the emergent ray is called the angle of the deviation‘d’. The angle of deviation depends on:    *  The ... Read more

Work and Energy - Work * Work done by force acting on an object is equal to the magnitude of the force multiplied by the displacement of the object in the direction of the force. Condition for work to be done:    *  A net force act on an object.    *  The object must ... Read more

Structure of Atoms - Structure of An Atom * An Atomic Number is the number of protons in an atom. * The arrangement of electrons in various energy levels of an atom known as electronic configuration * The maximum number of electrons in any energy level of the atom is given by 2n2. * The ...
