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).
What is Joule Cycle? Find the efficiency of the Joule cycle, consisting of two isobars and two adiabats. Presume that the heat capacities of the gas C p and C v are constan
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
Superposition principle The general idea is that, while a number of influences are working on a system, the total influence on that system is just the sum of the individual in
Your dog is running around the grass in your back yard. He undergoes successive displacements 3.50 m south, 8.20 m northeast, and 15.0 m west. What is the resultant displacement?
Write two characteristic features of nuclear force which differentiate it from the Coulomb force.
What are other manufactured wavelengths in Helium-Neon Laser? Then what remembers while there is mention of a He-Ne laser is a red beam, those along with other wavelengths are
A steam turbine takes in saturated steam at 300 C and outputs steam at 4 bar. If the efficiency of the turbine is 65%, calculate: a. The final composition (vapor vs. Liquid) of
In Thomson's effect we pact with only metallic rod and not with thermocouple as in Peltiers effect and Seebeck's effect. (That's why sometimes it is called as homogeneous thermo el
faraday law of induction(differential and integral form)
1. There are 40 such microwave hops in tandem. What is the end-to-end C/N of the link? 2. Assume now that these 40 hops are replaced by a single satellite hop as shown below.
