Energy gap: 1.4ev at room temperature
Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and arsenic is the fifth column neighbour of Gallium in the periodic table. The melting point is 13000C, makes the production of gallium arsenide of electronic grade and externally difficult one. Horizontal furnaces using zone refining technique have proved the best, but the resulting material is still is not competitive with silicon and germanium in the purity or structural perfection. It is used for Scotty diodes, light emitting diodes, gun diodes, and lasers.
Generate and plot a sampled sine wave with f s =8kHz, of 4 seconds duration, with frequency ω 0 = Π/10 and amplitude A = 1 . 2. The waveform equation is x ( n ) = A s
I don''t understand how pressure energy arises
How can we ger plane polarised light??
Energy is transferred in a one direction only. Example : Wave propagating in a stretched string.
Regard as two Styrofoam cups. Each one is on the end of its own neutral slender glass rod which serves as a handle. One of the cups has a fixed amount of positive charge consistent

Q. State Coulombs law in electrostatics? Coulomb's law declares that the force of attraction or repulsion between two point charges is directly proportional to the product of t
The formula y=A cos ?(t-x/v), describes a wave that moves in the +x direction along a stretched string. Show that this formula is a solution of the wave equation?
Determine the ratio of the frequencies of harmonics in an air column of same length in a) a closed pipe and b) an open pipe
