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.

Give a mathematical expression for linear width of principal maxima in case of single slit Fraunhofer diffraction.
Two travelling sinusoidal waves are described by the wave functions Y 1 = 55.00 sin [π (4.00 x - 1200 t )] Y 2 =55.00 sin [π (4.00 x - 1200 t - 0.250)] Where x ,
Q. What is an optical fibre and dispersion? Write the expression for angle of deviation.
They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current. Voltage is the electromotiv
