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 incorrect with this picture? Answer: The Current is the flow rate of charge. When the charge obtains to the junction of three wires (including the wire the
State Gauss's law. The total flux of the electric field E over whichever closed surface is equal to 1/ε o times the net charge enclosed by the surface. That is φ = q / ε
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
A ray of light falls on a glass slab of refractive index u.if the reflected and refracted rays are mutually perpendicular to each other,find the angle of incidence. Ans) let i b
It is the property of a material by virtue of which it allows itself to be magnetized. Permeability varies from material to material depending upon the saturation and temperature.
a) Describe how capacitance of a capacitor depends on area, distance among the plates and on the dielectric material. b) Draw electric field lines of a (i) positive poin
Color vision and chromatic aberration: One of the remarkable ability of the eye is its ability to see color. There are three types of cones that respond to light from three
