photoelectric effect waves

The Photoelectric Effect - There are three ways in which electrons eject out of a material. They are (i) Thermionic emission (ii) Field emission (iii) Photo electric emission In all the above cases, energy is given to the material but in different forms. If given in the form of ..

There are three ways in which electrons eject out of a material. They are (i) Thermionic emission (ii) Field emission (iii) Photo electric emission In all the above cases, energy is given to the material but in different forms. If given in the form of heat it is called as Thermionic emission, if in..

Waves carry energy from one place to another Transverse and longitudinal waves, Seismic waves Problems involving wavelength, frequency and wave speed Sound waves in a medium Radio waves, light and X-rays, electromagnetic waves..

Even before Sir Edward Appleton's pioneering work in 1925, it had been suspected that ionization of the upper parts of the Earth's atmosphere played a part in tile propagation of radio waves, particularly at high frequencies. Experimental work by Appleton showed that the atmosphere recei..

Superposition of Waves - When a number of similar waves pass through a medium simultaneously, each wave travels through the medium as though the others were not present. However, at any point in the medium, the net effect of the waves reaching that ..

. One end of a long rope is attached to a rigid support and the free end is given a sudden jerk, causing an up and down motion. The hump produced near the hand begins to move away from the hand. If the hand is repeatedly moved up and down, then instead of a pulse, a succession of pulses will follow..

The solar spectrum of electromagnetic waves include energy packed heat generating waves called radiation waves. As they lie beyond red colour waves of visible spectrum, they are also called 'infra-red rays'. These infrared rays lie in the wave..
