👉 Light particles, often referred to as photons, are fundamental entities that exhibit both wave-like and particle-like properties. These particles of light travel at a constant speed in a vacuum and carry energy proportional to their frequency, as described by Planck's equation. They are crucial in various phenomena, from the photoelectric effect to the operation of solar cells. In an interview setting, discussing light particles can involve explaining their dual nature, their role in quantum mechanics, and how they interact with matter, such as in absorption, emission, and scattering processes. This topic bridges classical physics and modern quantum theory, making it a rich area for exploring scientific principles and their applications.
