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
Artificial satellites 1. Satellites help to develop reliable communication links between different countries separated by large distances on the globe. The communications inclu
Describe Acceleration In physics, acceleration is the rate at that the velocity of a body changes with time. In common, velocity and acceleration are vector quantities, along w
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
Calculate the heat required to melt 316.7kg of potassium metal at 336 K. The enthalpy of fusion of potassium is 2.35 kJ mol -1 .
Write the commands that will create the following matrix. You can use only special matrix commands: Two cars started to move from zero position with (φ = 35o) as shown. F
Phase advancers: Phase advancers are used to better the power factor of induction motors. The low power factor of an induction motor is because of the fact that its stator winding
The rate of flow of energy or particles across a given surface.
Q. In the given circuit, calculate the potential differences across each resistor Solution : i) R s = R 1 + R 2 + R 3 = 10Ω ii) Current in circuit I = V/R s
The temperature co-efficient of resistance: The temperature co-efficient of resistance is defined as; The Fractional change in resistance from 0ºC, per degree temp
