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
What is time? 1. This is the question that each true scientist dreads to be asked especially in a public setting by extremely inquisitive young learners. We have learned to ca
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of

Gauss' law (K.F. Gauss): The electric flux by a closed surface is proportional to the algebraic sum of electric charges contained in that closed surface; in differential form,

How to calculate change in entropy.
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
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
