Microwaves and Radio waves:
Microwaves are produced by high frequency electromagnetic oscillators in electric circuits. Microwaves are electromagnetic waves with wavelengths in the range 10 m m to 10 m.
Radio waves are produced by accelerated electrons in suitable electronic circuits. Radio waves have wavelengths from 1m to 100km.

What do you mean by Doppler effect? Derive a mathematical expression for the apparent frequency of a note, when source of sound and observer are approaching each other.
It determines the probability of an electron occupying a state at an energy level E. This takes into account that a collection of electron must obey the Pauli Exclusion Principle.
A plane polarized monochromatic light of wave length 5893Å is incident perpendicularly on a quarter wave plate to produce elliptically polarized light. If the refrac
In the figure below the closed surfaces A and B appear as closed curves. Find the flux through closed surface B.
Can anyone give me a clear picture of GRAVITY?How does it works and and where does it pulls everthing?
1. Cell growth. if V is the volume of a spherical cell, then, in certain cell growth or for some fetal growth models, the rate of change of V is given by dV/dt =kV2/3, where k
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
Actually vectors are divisible but not directly. A vector is multiplied by the inverse of the vector to be divided.In other way, its magnitude an be divided and multiplied by a uni
