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.
#questi1. A sound with a frequency of 261.6 Hz travels through water at a speed of 1435 m/s. What is the wavelength of the wave? a. 1.83 x 10 -1 m b. 3.753 x 10 5 m c. 5.486 m
After the parallel algorithm has been written as well as executed performance of both algorithms is one of other main concerns. In order to examine performance of algorithms there
Factors which are affect velocity of sound in gaseous medium is (1) Effect of density (2) Effect of pressure (3) Effect of temperature : (4) Effect of humidity
what is gravity caused by and what is its exact pull
what is wedge constraint? explain with example.
A 4μF capacitor is connected in parallel with a 6μF capacitor. This arrangement is then linked in series with a 10μF capacitor. A supply p.d. of 250V is linked across the circ
"It is explaining that at similar temperature and pressure equivalent volumes of all gases contain similar number of molecules".
How to find acceleration from succesive speed?
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.
