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
Photoelectric electricity is produced directly from solar energy when which following are absorbed in a semiconductor to create an electric current? a) Protons b) Electron
Making a jam jar aquarium If a large glass tank is not available, practically any glass vessel can be used as a easy aquarium if it is well stocked with submerged water plants
Determine current flowing through 5 ? resistor in the circuit demonstrated in Figure. Use Source transformation technique. Ans: Determination of current flowing thr
A pendulum is timed, first for 20 swings and then for 50 swings Time for 20 swings= 17.4s Time for 50 swings= 43.2s Calculate the average time per swing in each case.
Minimum amount of light for low vision If 90 photons enter the eye ,10 or less are actually absorbed in photoreceptors. About 3% are reflected at the surface of the corne
Static limit: The distance through a rotating black hole where no observer can probably remain at rest (w.r.t. the distant stars) due to inertial frame dragging; this region i
Average acceleration is described as the change in velocity over a given time interval Δt. Hence, The instantaneous acceleration of given particle is the rat
The current induced in the conductor due change in magnetic field is called eddy current.we study more about this in electro magnetic laws.
Explain vectors Vectors : a quantity that has a size as well as direction is known a vector. So, for example, the wind blows with some speed and in some direction. So the win
How a CPH products? Answer; no time has passing of a CPH. Thus, CPH exists and never decay.
