Basic concepts of electromagnetic spectrum:
BASIC CONCEPTS
1. When Sun light falls on a prism, the transmitted light produces a sequence of colours called 'Spectrum'.
2. A spectrum is a group of wavelengths or frequencies.
3. Colour is a sensation in the brain due to the execution of retina, by an electromagnetic wave of some particular wavelength.
4. The unit of wavelength is Angstrom. It is denoted by Å.
5. 1Å = 10-10m or 10 cm.-8
6. When white light falls on a prism it gives a Spectrum of 7 colours. The seven colours are Violet, Indigo, Blue, Green, Yellow, Orange and Red.
7. Wave length of Violet colour is 4460Å to 4000Å.
8. The radiations having wavelengths less than 4000Å (Violet) are called Ultra Violet radiations (UV).
The line integral of the magnetic flux about a closed curve is proportional to the algebraic total of electric currents passing through that closed curve; or, in differential form,
what are the examples of accurate and precise
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
Define free vector
Examples of systems in equilibrium: a) a stone resting on the ground; b) a pencil balanced on your finger; c) a ladder placed against the wall, an aircraft flying at a co
Weiss constant: A characteristic constant based on the material, utilized in calculating the susceptibility of paramagnetic materials.
Basic principles of spectrophotometry: An absorbance spectrophotometer is an instrument that measures the fraction of the incident light transmitted through a solution
in need of projects on '' PHYSICS OF THE BRAIN''. Thanks
what is non conventional sources?
The characteristics of substance by virtue of which it opposes the flow of current by it, is called as the resistance.
