## FAQs on Dual Nature of Radiation & Matter in One Shot (NCERT) Video Lecture - Physics Class 12 - NEET

 1. What is the dual nature of radiation and matter?
Ans. The dual nature of radiation and matter refers to the fact that both radiation and matter exhibit characteristics of both particles and waves. This means that they can behave as discrete particles, such as electrons or photons, and also display wave-like properties, such as interference and diffraction.
 2. How does the dual nature of radiation and matter explain phenomena like diffraction and interference?
Ans. The dual nature of radiation and matter explains phenomena like diffraction and interference by considering that particles, such as electrons or photons, can behave as waves. Diffraction occurs when waves encounter an obstacle or aperture and bend around it, creating a pattern of interference. Interference occurs when waves overlap and either reinforce or cancel each other out, resulting in a pattern of light and dark bands.
 3. Can you provide an example of how the dual nature of radiation and matter is observed in everyday life?
Ans. One example of the dual nature of radiation and matter in everyday life is the phenomenon of electron microscopy. In electron microscopes, a beam of electrons is used instead of light to image objects at very high magnifications. Electrons, which are particles, display wave-like behavior and can diffract off the surface of the object being imaged, allowing for detailed observation and analysis.
 4. How does the dual nature of radiation and matter impact our understanding of the atomic structure?
Ans. The dual nature of radiation and matter is crucial to our understanding of the atomic structure. It helps explain the behavior of electrons in atoms, particularly their orbits and energy levels. According to the wave-particle duality concept, electrons can be thought of as both particles and waves, occupying specific energy levels around the nucleus of an atom.
 5. What are the practical applications of the dual nature of radiation and matter?
Ans. The dual nature of radiation and matter has various practical applications. It is utilized in fields such as medical imaging, where X-rays, which have both particle and wave properties, are used to create detailed images of the human body. It is also essential in the development of technologies like electron microscopy, which allows for high-resolution imaging of microscopic structures. Additionally, the understanding of the dual nature of radiation and matter is fundamental in areas such as quantum mechanics and particle physics.
