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.
A popular toy on the market some years ago was the water rocket. Water (at 10°C) was loaded into a plastic rocket and pressurized with a hand pump. The rocket was released and woul
Double-slit experiment (T. Young; 1801): A popular experiment which illustrates the wave nature of light (and indeed of other particles). Light is passed out from a small sour
Can you please give me feedback on my physics assignment.
Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te

Define angle of repose Consider a body resting on a plane OA. Assume this plane OA is slowly raised from the horizontal position to incline it with the horizontal.
Excitation of Modes in Fiber A multimode fiber is used to couple light into a single mode fiber. Both fibers have the same total diameter. Explain the coupling. Use
What are sheathed fibers? The optics, which has an external cladding whether transparent or opaque, affords a mechanical protection to the optics.
what is viscosity?
According to Reynolds, the critical velocity (vc) of a liquid flowing by a long narrow tube is (a) Directly linked to the coefficient of viscosity of the liquid. (b) Inversel
