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...
Red-shift describes the phenomenon whereby the wavelength of light from a source increases as it travels through spacetime, hence observed as being 'shifted' to the red end of the spectrum (as red light h...
Thermal conduction is one of three types of heat transfer. It occurs when 2 objects are in contact and have a difference in temperature. The kinetic energy is passed on from the warmer object to the coole...
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 cre...
