All About Electron, Photon and X-Ray - Download Notes (JEE Main)

What is Electron?

An electron is a subatomic particle that carries a negative charge and is one of the fundamental constituents of matter. Electrons are found outside the atomic nucleus in energy levels or shells. They have a mass that is approximately 1/1836th the mass of a proton, making them much lighter. Electrons are responsible for various properties of matter, including their electrical conductivity and chemical behaviour.

What is Photon?

A photon, on the other hand, is a fundamental particle of light and electromagnetic radiation. It is the quantum of electromagnetic energy and does not possess mass or charge. Photons travel at the speed of light and exhibit wave-particle duality, meaning they can behave as both particles and waves.

What is X-Ray?

X-rays are high-energy electromagnetic radiation used for medical imaging and scientific research. They can penetrate matter, creating detailed images of internal structures like bones. X-rays are also used for industrial inspections and for analyzing atomic structures. While useful, precautions are needed due to their ionizing nature.
