Watching out for pseudoscience in physics articles and categories (see the list of these topics). Keeping the Physics Portal in good shape. Keeping the WikiProject Physics community active, growing, and well-supported. Discussing the content of physics articles on Wikipedia and what direction WikiProject Physics should take (see talk page).
Benjamin Franklin's experiment with bells and a lightning rod has remained a popular example of electric phenomena in modern times. The experiment has been adapted and updated, and is now commonly used in classrooms and demonstrations to illustrate a variety of concepts related to electricity.
Science class X Experimental projects, [1] also known as investigatory projects, start with a question (AKA a hypothesis), use the scientific method to complete the research, and end with a report detailing the results and conclusions and an abstract.
Fig. 1: Underwater plants in a fish tank, and their inverted images (top) formed by total internal reflection in the water–air surface. In physics, total internal reflection (TIR) is the phenomenon in which waves arriving at the interface (boundary) from one medium to another (e.g., from water to air) are not refracted into the second ("external") medium, but completely reflected back into ...
Gilbert's versorium. The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects this by the movement of a test charge due to the Coulomb electrostatic force on it.
Physics of the term [ edit ] Fig. 2 : Linearly-polarized (plane-polarized) sinusoidal electromagnetic wave in an isotropic medium, propagating in the x direction (the ray direction and wave-normal direction), with the electric field vectors E and D in the y direction, and the magnetic field vectors B and H in the z direction.

The experiment belongs to a general class of "double path" experiments, in which a wave is split into two separate waves (the wave is typically made of many photons and better referred to as a wave front, not to be confused with the wave properties of the individual photon) that later combine into a single wave.
