Following the Einstein’s 1905 paper on photoelectric effect, the concept of particle nature of light took birth in the physics community, which stated that light is composed of many small particles known as photons. When the light or any electromagnetic radiation with high frequency strikes on the metal surface, it emits photoelectrons from the metals. Similarly when X-rays are incident on elements with low atomic number, elastic interaction takes place resulting in change in the wavelength of scattered beam along with the change in direction. Further, when γ-rays interact with matter, then it gets disappeared and converts itself into electron-positron pair known as pair production. Through this article we have attempted to study the particle nature of light and how it interacts with matter under the certain conditions to form new physical phenomena, and their applications to determine the crystal structures, Gravitational Red shift, Information on Black Holes and for Medical purposes.
