WebThe remainder goes into the ejected electron’s kinetic energy. In equation form, this is given by. K E e = h f − B E, 21.6. where K E e is the maximum kinetic energy of the ejected electron, h f is the photon’s energy, and BE is the binding energy of the electron to the particular material. WebThe speed of an electromagnetic wave in the vacuum medium is. c = 1 / μ 0 ε 0. Here, the value of c equals the speed of light from the measuring optical instruments. Light is also an electromagnetic wave that means it …
