Polarization
Light is defined in previous article However, a wave is free to oscillate right and left or up and down or at any angle between…
Young’s experiment
Thomas Young first demonstrated interference from light waves with a double slit in 1801. The schematic diagram for this experiment is shown in below…

Millikan’s Photoelectric Experiment and Measurement of Planck’s Constant
The experimental arrangement of Millikan’s method to determine Planck’s constant ‘h’ is shown below. The apparatus consists of an evacuated chamber (vaccum) where different…
Einstein’s photoelectric equation
Einstein gave an explanation for photoelectric emission based on the Planck’s quantum theory of light. When light of certain frequency (greater than threshold frequency)…
Hertz Photoelectric Effect
Hertz, in 1887 discovered the phenomena of photoelectric effect for the first time. He was experimenting on the generation of electromagnetic waves by spark…
Photoelectric Effect-Dual Nature of Radiation and matter
The Definition of Photo electric effect given in above article. The phenomenon of emission of electrons from a metallic surface by the incidence of…
Electron Emission- Dual Nature of Radiation and matter
Free Electrons move randomly in a conductor due to attraction of positive charges. So some energy is required to emit electrons from metal surface….
