Q. Define: optic axis of a crystal.
In a double refracting crystal there is a particular direction in which both the rays travel with same velocity. This direction is called as optic axis.
The refractive index is similar for both rays and there is no double refraction along this direction.
Q. Compute the resistance of the filament of a 100W, 220 V electric bulbs. Power P = V 2 /R Resistance R = V 2 /P = (220 X 220)/ 100 = 484 ohm.
