Photoelectric Effect - Lecture Notes 2
, 1. Introduction to Light and Matter Interaction
Before deep diving into the specific lecture slides, it is extremely essential to understand the scientific
dilemma of the late 19th century. Classical electromagnetic wave theory proposed by James Clerk
Maxwell described light strictly as continuous waves propagating through space.
According to this classical framework, when light waves strike a metal surface, the continuous electric
field vector of the wave exerts a force on the free electrons within the metal. The energy carried by these
waves should be absorbed continuously by the electrons over time. Thus, classical theory predicted that if
the light source is intense enough, it should impart enough energy to free the electrons, regardless of the
light's frequency or color. However, experimental realities completely contradicted this view, giving rise
to quantum mechanics.
