What is Wien’s Law?

Global Optics

Editorial Team - GoPhotonics

Aug 21, 2023

Wien’s law, also known as Wien’s displacement law, describes the relationship between the temperature of an object and the peak wavelength of light it emits. It states that the product of ...read more

What is Huygens' Principle?

Global Optics

Editorial Team - GoPhotonics

Sep 22, 2023

Huygens' principle is a fundamental concept in optics which postulates that each point along a wavefront can act as a point source, emitting secondary spherical wavelets that propagate forward at ...read more

What is Snell's Law?

Global Optics

Editorial Team - GoPhotonics

Sep 19, 2023

Snell's Law, also known as the Law of Refraction, is an equation that connects the angle of the incident light and the angle of the transmitted light at the interface of two different media. The l...read more

What is Fermat’s Principle?

Global Optics

Editorial Team - GoPhotonics

Sep 22, 2023

Fermat’s principle, also known as the Principle of Least Time, states that light follows a path of minimum time when it travels from one point to another. It considers the quickest time to cover...read more

What is Bragg's Law?

Global

Editorial Team - GoPhotonics

Mar 9, 2023

Bragg's Law is a fundamental principle in physics that explains how X-rays and other types of electromagnetic radiation can be used to determine the structure of crystals. Bragg’s Law is use...read more

What is Blackbody Radiation?

Lasers

Editorial Team - GoPhotonics

Feb 12, 2023
