General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. Wh...
A Michelson interferometer is a type of device that splits a beam of light, bounces the two beams off of separate mirrors, and...
The space we are in remains the same, but the space around us is changing. Thus, our little pocket of space is moving, but we inside it do not. We can move faster than the speed of light because of this, for space is moving and not something in space-time, and it does not viola...
fields, the Michelson interferometer reveals manifestations of the transverse and longitudinal spatial (rather than temporal, as it is commonly adopted) coherence of the optical field; the purely temporal coherence of the optical field is revealed only under special conditions of the interference ...
What is an optical fiber and how does it work? Total internal reflection Snell's law of refraction relates the incident and refracted angles for a light rays striking the interface between two media with different refractive indexes, n1
What is a Helmholtz coil used for? What is Faraday's first law of electromagnetic induction? Why do you place a key, in parallel with the galvanometer? What is a thermistor? What is an ultrasonic interferometer? What is ultrasonic interferometer? What is displacement current? What is the she...
In various optical applications, if you want to use light to achieve the purpose of application, you need to control the light, including direction, phase and so on. And these adjustment control, need the corresponding adjustment tools. In addition, because the wavelength of light is generally ...
