Surface Chemistry Introduction
Surface chemistry is a branch of chemistry which deals the phenomenon of occurring at the interface of two phases. The interface between two phases…
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)…
