Distance travelled by light in a time interval of one planck time, the shortest distance possible, is 10 - 4 3 ..

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiation and energ..

The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n..

The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h ..

5. Calculate the energy of a photon of light having frequency of 3.0 x 10 1 5 sec - 1 (Planck's constant h = 6.63 x 10 - 3 4 J..

Photocells are used in television camera to reproduce sound recorded on films, in counting devices, in burglar and fire alarms, to measure the temperature of stars, to study the spectrum of heavy bodies, to operate street light, to compare the illuminating powers of two sources, in photometer..

In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: * An atom consists of a small, heavily positively charged nucleus around which electrons revolve in definite circular paths called orbit..

The energy of a photon is given by E = h n where the frequency of light = 3.0 x 10 1 5 s - 1 Planck's constant, h = 6.63 x 10 - 3 4 J s E = (6.63 x 10 - 3 4 J s) x (3.0 x 10 1 5 s - 1 ) = 6.63 x 3 x 10 1 9 J = 1.99 x 10 -18 ..

. have also dual character. In other words, the microscopic particles in motion possess both the particle and wave characteristics. Thus, according to de-Broglie, "all material particles in motion possess wave characteristics". According to de-Broglie, the wavelength associated with a particle of m..
