ENERGY LEVELS
The energy levels, measured in electron volts (e.v.) in which orbiting electrons exist comply with a law of physics which states that energy can be given to electrons only in discrete amounts (quanta) which means that there are energy values that an electron cannot acquire. From this it can be deducted that there is a forbidden energy gap between each of the allowed energy bands K to O.
The width of the forbidden energy gap between the top of the valence band and the bottom of the conduction band determine the electrical conducting properties of materials.
The central part (photosphere) of the sun is very hot and all possible wavelengths of the visible light. Though, the outer part (chromospheres) having of vapours of dissimilar com
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
Eye Chamber: The ball is separated into two chamber, the aqueous chamber and the vitreous chamber. Working: Parallel rays from an object converged by the eye lens and b
The discovery of neutron becomes very late because: (1)Neutrons are present in nucleus (2)Neutrons are highly unstable particles (3)Neutrons are chargeless (4)Neutrons
