, Introduction
The universe manifests two things; matter and radiation. All objects are made up of matter particles
such as atoms and molecules, but radiation consists of "photons” tiny particles made of waves of
electromagnetic (EM) radiation (Chemistry LibreTexts, n.d.). Not all EM radiations are visible
except for light. Light itself is the ultimate source of energy; for instance, the Sun in our solar
system is the source of energy for all living organisms. plants produce their food with the help of
Sunlight, in turn, Animals and Human beings rely on these plants to survive.

In fact, the Suns energy powers the flow of winds, water on earth, and creates fossil fuels for over
a period of millions of years, also providing light and warmth on Earth.
Background
Light is a form of EM radiation that is visible to the naked eye (Stark, 2024). The very nature of
light has been the subject of discussion and debate since the time of Greek philosophers some 2500
years ago. It is no wonder that scientists have been fascinated by light and many have devoted
much of their lives to trying to unravel its mysteries.
The main issue was to come up with a single theory that explains the different phenomena
exhibited by light like; reflection, refraction, rectilinear propagation, interference, difraction,
polorisation and photoelectric effect. For example, Isaac Newton proposed the Corpuscular theory
