Each pure metal substance requires a different minimum threshold frequency of light to eject an electron. Albert Einstein (1879‐1955) explained this phenomenon by hypothesizing that light has properties similar to what? What are these “pieces” of light called?
Homework Answers
Photoelectric effect is the phenomena of emission of electrons from a metal when it is struck by light of a minimim frequency (called threshold frequency of that metal).
Albert Einstein gave the theory of dual nature of light. Light has characteristics of both a wave and a particle. The pieces or packets (containing a minimim amount of energy called quantum) of light are called Photons. The energy of these photons can be given by Planck's equation
E=
Where
h=Planck's constant=6.626 x 10-34 J-s
c=speed of light=3x108 m/s
