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.
Q. Illustrate how do you find the refractive index of a liquid by using total internal reflection? Answer:- Using Snell's law n (1) = (n (2) x sin angle (2)) / sin angl
What do you mean by dispersion? Describe a physical quantity which depends only on the material of the prism for its dispersion. Get an expression for it.
In these diodes electron and hole pairs are formed by junction photoelectric effect. That is the covalent bonds are broken by the EM radiations absorbed by the electron in the V.B.
No;(Personal Note:Please Rate this and let me know if this helps) Reason: From the quantisation of charge charactersistic, we can say that charge comes in integral multiple of e (
