The Feynmann diagrams show two electroweak interactions between electrons. One of the exchange particles is a photon.

The discovery of the Higgs Boson marked a huge accomplishment for particle physicists.

It was first hypothesised by Peter Higgs and his team in 1964 and then discovered by a large collaborative effort at the CERN particle physics laboratory much later in 2012.

A ray of light passes from air into a glass prism.

As the light ray passes through the prism, it emerges back into the air.

The prism is rotated and one side is coated with a film of transparent gel. A ray of light strikes the prism, at an angle of incidence of 38°, and continues through the glass to strike the glass–gel boundary at the critical angle.

A ray of light now strikes the prism at an angle of incidence which means that it now refracts straight through the gel at the glass–gel boundary.

The graphs shows how pressure, p, varies with absolute temperature, T, for a fixed mass of an ideal gas.

The force acts on a mass of 5.0 kg initially at rest.

An industrial kiln is used for ‘firing’ ceramic and pottery items at very high temperatures.

The kiln emits electromagnetic radiation of peak wavelength, λ_max = 3.75 × 10⁻⁶ m and has a surface area of 150 m².
