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.

Two vibrating particles that are "out of phase" differ in the phase of their vibration by: a) 1/4 cycle b) 1/2 cycle c) 3/4 cycle d) 1 cycle Ans: Two vibra
Provide the conditions needed for production of a sustained interference pattern.
A 9.0-kg crate sits on a level, rough floor. A 61-N force is required just to begin it moving. What is the size of the coefficient of maximum static friction?
Interference of waves: When two waves of similar amplitude and period traveling in the similar medium superpose, they reinforce each other at one point and cancel at others. Th
