Einstein proposed three tests of his own tests of general relativity when he first published it in 1915: the precession of Mercury’s orbit, the bending…

Hafele–Keating Experiment is so tampered with that it could be considered fraudulent. It was a test of the theory of relativity. In October 1971, Hafele…

Franck–Hertz Experiment is demonstrated the existence of excited states in mercury atoms, helping to confirm the quantum theory which predicted that electrons occupied only discrete,…

Double-Slit Experiment belongs to a general class of “double path” experiments, in which a wave is split into two separate waves that later combine into…

Davisson-Germer Experiment is the first measurement of the wavelengths of electrons. It is a physics experiment conducted by American physicists Clinton Davisson and Lester Germer…

Cavendish Experiment used a torsion balance device to attract lead balls together, measuring the torque on a wire and equating it to the gravitational force…

Experimental Physics is in the areas of fluid dynamics, molecular physics and atmospheric physics. It is the category of disciplines and sub-disciplines in the field…

Main objective of this lecture is to present on Wave Properties. Here briefly focus on Reflection: the turning back of a wave when it reaches the boundary of the medium…

Philosophy of Thermal and Statistical Physics in part of the philosophy of physics whose subject matter is classical thermodynamics, statistical mechanics, and related theories. This…

Principle objective of this lecture is to present on review of Basic Algebra. Algebra is the branch of mathematics that uses letters in place of some…
