Dispersion and Impure Spectrum:
Dispersion : The phenomenon due to which a polychromatic light splits into component colours, when passed through a prism is called 'dispersion'.
Impure Spectrum : A Spectrum in which various bands of colours have no sharp well defined boundaries, but merge in each other is called 'Impure Spectrum'.
Pure Spectrum : A Spectrum in which various bands of colours have sharp well defined boundaries and do not merge in each other is called 'Pure Spectrum'.
The angle through which light of particular wavelength can deviate, while passing through a prism is called 'Refrangibility'. The refrangibility for red light is least whereas for the violet light is maximum.
Wavelengths of g - rays are ranging from 0.0001nm to 0.1 nm. (or) 0.001 A to 1A0
In this type of capacitors the dielectric consists of an extremely thin film of aluminium oxide formed on one of its aluminium foil plates. Intimate contact with the other plates i
Centrifugal force with a tin can lid Punch a hole near the edge of a tin can lid. Attach it to the cord from the drill and view the effects of rotation.
Passive network:- It can be described as a network, which contains no source of e.m.f. in it.
State the importance of emission and absorption spectra. Derive the mathematical expression for refractive index of material of the prism.
Q. What is Fresnel diffraction? a) The source as well as the screen are at finite distances from the obstacle producing diffraction. b) The wave front suffer diffraction is
Explain displacement x(t) is known as displacement and it denotes the position of a body at time. If the displacement is positive then that body is to the right of the chosen
working and principle
Spark suppression: If we consider a circuit with a large inductance, possibly one using a magnetic relay. At the instant the switch is opened, the current through the coil is
If a great point-mass is removed by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is known as a simple pendulum.
why at critical temperature in superconductors resistance becomes zero? Solution) For conductors as the temperature increases their rasistance increases and as temperature decreas
