a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.

If electrons are fired through a thin piece of graphite towards a screen an interference pattern forms.We can explain this by thinking of the electrons as having a wavelength, called the de Broglie wavelengt...

Consider a single photon (a particle of light) of a particular energy striking the surface of a metal. If the energy of this photon exceeds the work function of the metal, it will remove a single electron - ...

Light firstly goes through a single slit, this makes light coherent and monochromatic. Then, light diffracts on the double slit, undergoes superposition and constructively and destructively interferes creati...

The direction of the conventional current is from positive terminal to negative terminal. The direction of electron flow is from negative terminal to positive terminal. This is because electrons are a negati...
