Q. Briefly explain working of Michelsons Interferometer?
Michelson designed an instrument for the measurement of wavelength of sodium light, thickness of thin film and for many applications. The instrument is based on principle of interference of light known as Michelson's Interferometer.
It is based on principle of interference of light by the way of division of amplitude. According to this the incident beam is divided into two parts and sent into two perpendicular directions and brought back together by using plane mirror to interface each other.
By what percentage should the pressure of a given mass of gas be increased,so as to decrease its volume by 10% at a constant temperature.
You''ve recently wired up an experiment in the lab. Part of the experiment involves having two long wires extended 2 meters below the ground. One day, the experiment stops working.
After being launched, a rocket attains a speed of 122 m/s before the fuel in the motor is completely used. If you suppose that the acceleration of the rocket is constant at 32.2 m/
Fibre optics: Light travels in straight lines, even though lenses and mirrors can deflect it, light still travels in a straight line between optical devices. This is fine for

At 400.0 K, germanium has 1.13 x 10 15 free electrons/cm 3 . How many free electrons per Ge atom are there at this temperature? At 400.0 K, silicon has 4.54 x 10 12 free
Air Resistance Force (Fair) : special type of frictional force that acts upon objects as they travel by the air. Force of air resistance is often observed to oppose the motion of a
Describe Kirchoffs Current Law? Ans. It defines " the current flowing toward a point in a circuit have to be equal to the current flowing away from that point. I = I 1 + I
4 transitor bias circuit
Consider a current loop where the circulating current is I. This may be for an example of a coil carrying a current. We will assume that the current loop lies within a single plane
