Time dilation is an actual difference of elapsed time between two events as measured by observers either moving relative to each other or differently ... more
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions. If an electron ... more
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable ... more
