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.
blackbody radiation The radiation the radiance at specific frequencies all across the spectrum generated by a blackbody i.e., a perfect radiator (and absorber) of heat. Physic
Insulators: Insulators are those substances which do not permit to pass electric current by them. e.g. Wood, Plastic, rubber, glass etc
An electron, an alpha-particle and a proton have the similar kinetic energy. Which one of these particles has the main de-Broglie wavelength?
Using a wheel and axle Use the pencil sharpener that you used in experiment A 8. Pull on the end of the string that held the books and observe how rapidly the crank turns.
1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
Motion Animation A car along with a non-zero initial speed has a constant acceleration whose value could be controlled through the user.
