BASICS OF X-RAYS

TOPIC: BASICS OF X-RAY

🌟 IMPORTANT POINTS TO REMEMBER

🔹Hard rays: X-rays having shorter wavelengths have great penetrating power and are called hard rays.

🔹Soft rays: X-rays having longer wavelengths possess less energy and less penetrating power. These are called Grenz rays.

🔹Thermionic emission: It can be defined as the phenomenon of emission of electrons by metal when it is heated. The electron stays in an electron cloud until a high-voltage circuit is activated. The electron emitted under this action is called thermion.
