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
When a system returns back to its initial state after passing by dissimilar phase, the phenomena is said to be a cyclic process. In this process as ΔU = 0. From first law of the
A 2.0 kg tumor is being irradiated by a radioactive source. The tumor receives an absorbed dose of 12 Gy in a time of880 s. Each disintegration of the radioactive source produces a
Lenz's law (H.F. Lenz; 1835): An induced electric current always pass in such direction that it opposes the change generating it.
Step to improve Power Factor By using static capacitor: Static capacitor is generally used to get better the power factor of the power system. As the capacitor draws leadi
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
When a pulse is reflected from a free side, then there is no changing of medium. Crest (C) represents as crest (C) and trough (T) denotes as trough (T), Time changes by zero and
Vibratory and Oscillatory Motion : To and fro or back and forth motion of an object is known as vibratory and oscillatory motion.
How do I find the momentum, velocities and energy of both vehicles as they leave the impact point, the energy transferred during the collision and the momentum and energy of the ve
A certain machine exerts a force of 200 newtons on a box whose mass is 30 kilograms. The machine moves the box a distance of 20 meters along a horizontal floor. What amount of wor
