What is diffraction of light? Illustrate a graph showing the variation of intensity with angle in a single slit diffraction experiment. Write single feature which distinguishes the
observed pattern from the double slit interference pattern.
How would the diffraction pattern of a single slit be affected when?
(i) The width of the slit is reduced?
(ii) The monochromatic source of light is changed by a source of white light?
If the thickness of the slab is increased what happens to lateral shift?
what is the angle of incidence when the refracted and the reflected ray are parallel to one another? does this angle depend on the wavelength of light? Ans) The angle of inciden
current gain equations in 3 configurations.
It is the degree or extent by which magnetic lines of force can enter a substance and is expressed by µ.
The mass of 1 mole of electrons is: (1) 9.1x 10 -28 g (2) 1.008mg (3) 0.55mg (4) 9.1x 10 -27 g Ans: (3)0.55mg
Explain the term poly elastic and give some of example.
Get expression for intensity of the diffracted beam by single slit. Explain the position of minima and maxima.
This is the virtue of a material resists flow of electric current. It should be as high as possible. When material is subjected to an electrical pressure then will always be a flow
A single turn coil of radius 5cm is placed on a plane paper and magnetic flux, directed perpendicularly out of the paper changes according to φ = 11t 2 + 7t + 15. Determine the ma
The effects of short circuits: A short circuit is a path for current where a path should not exist, the path is generally considered to have a low resistance. If a short circui
