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.
Although it needs not concern us further, we also consider that the flow is irrotational. To check for this property, let a tiny grain of dust goes with the fluid. Although this te
If in a thermoelectric series current flows from the metal occurring earlier in the series to metal occurring later through the cold junction, why in a copper-iron thermocouple, th
What is the difference among Free Electron Theory and Band Theory of solids? Free Electron Theory: This theory says that, metals conduct electricity due to the presence of
Q. Why nichrome is used as heating element in electric heating devices? Nichrome, an alloy of nickel as well as chromium is used as the heating element for the following reaso
3 . 50 nC of charge is consistently distributed in a solid Styrofoam ball of radius 2 . 00 cm cantered at x = 2 . 00 cm on the x-axis of a Cartesian coordinate system. -1 . 25 nC o
What is a thin prism? Write the mathematical expression for deviation produced by a thin prism.
A spacecraft design similar to GEOSAT proposes to use passive gravity-gradient stabilization for pitch attitude control (motion about the y-axis). The satellite consists of a tip
In laboratory frame of reference, particle A moves along X direction with velocity 0.5 c and particle B moves along Y direction with velocity 0.4 c. Evaluate velocity of particle B
Inductors can be classified on the basis of nature of value and type of core used. Different type of inductors based on the type of core is: AIR CORE INDUCTORS: Air core coils
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
