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).
Q. What is a power? Answer: That seat of EMF" reply is SO wrong. Not merely is the rate of charge delivery not power but a seat of EMF doesn't deliver charge. A seat of EM

In solids, heat is move from conduction. We will study conduction of heat energy by a solid bar in the following section. Given a solid bar of thickness and area of cross-sectio

Which of the answers listed below best completes the statement: The rate at which any part of a wave travels from one place to another determines the waves: a) Propagati
With the help of neat & labelled diagram. Explain the principle & working of a moving coil galvanometer. What is importance of radial magnetic field.
A monochromatic parallel beam of light is incident on a single slit. Graphically show the intensity distribution among the secondary maxima and principle maxima in diffracted beam.
how to calculate wave function of particle?
Intensities of an ordinary light and laser light The intensity (I) of a wave is the energy per unit time flowing through a unit normal area. The light from an ordinary light so
Light with a wavelength of 454.5 nm passes by two slits that are 95.2 cm from a screen. The distance among the centers of the central band and the first-order band is 15.2 mm.
