Einstein's famous equation e=mc^2 has shown that energy and mass are interconvertible. The kinetic energy of the particles in the nucleus is potentially available for their liberation as radiation, which loses its identity on transformation into electromagnetic waves. The matter thus seems to possess dual nature, capable of assuming either form. A piece of matter and a piece of radiation behave as waves in some experiments and as particles in other experiments. It is difficult to imagine the dual nature of matter and radiation with our daily experiences. For example, we feel hot when exposed to sunlight, which is made up of photons with higher energy. Then how do high-energy X-rays interact with matter and produce heat? These questions may puzzle us, but experiments have convincingly answered them. It can be illustrated using an analogy: waves involved in ocean water and ocean water itself. They appear different to the human eye because of their vastly different properties, such as wavelength and mass density. Electromagnetic waves and matter exhibit a similar dual nature.

How Do You Understand the Dual Nature of Radiation and Matter?

It is quite difficult to imagine the dual nature of radiation and matter with our daily experiences. For example, we feel hot when exposed to sun rays. Then how do high-energy X-rays interact with matter and produce heat? These questions may puzzle us, but they have been convincingly answered by experiments that have shown that a beam of radiation and a beam of particles such as electrons behave like waves and like particles in different experiments. Our teaching staff is very experienced, and they will guide you through the tough concepts of NCERT books. This is one of the best solutions for Class XI and XII.

Similar to how we understand that waves involved in ocean water and ocean water itself are different, even though they appear similar because of their vastly different properties such as wavelength and mass density, a similar dual nature is exhibited by the electromagnetic waves and matter.

The dual nature of radiation becomes evident in experiments involving the scattering of particles, photoelectric effect, Compton effect, pair production and pair annihilation. We shall discuss these phenomena one by one to understand their significance.
