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
#questionwho is albert einstein..
Adding 3 Vectors A simple demonstration of adding 3 vectors graphically. Also elaborates in which vector addition is relative.
Given below are two electric circuits A and B Measure the ratio of power factor of the circuit B to the power factor of circuit A.
For an infinite sheet of positive charge, the electric field lines: a) Run parallel to the sheet of charge b) Are perpendicular to the sheet of charge and point in toward
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
The magnetic induction at a point 15 cm from a long straight wire carrying a current is 4 X 10 -6 T Compute the current. (J - 12) B = μ o I/2πa I = 2πa X B/μo Current I
what is energy and its type?
In general the total energy of a harmonic oscillator having of two parts, potential energy (P.E) and kinetic energy (K.E.), the former being because of its displacement from the m

Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
