Understanding X-rays: Differences from General Light and Their Applications

This presentation by Shobhan, a lecturer in the Department of Physics at Milestone College, Dhaka, focuses on Chapter Twenty-Four of Modern Physics for Class IX. Students will learn about the production of X-rays, their differences from general light, and their classification and uses in medical science, industries, and detective work. The session will cover the properties of X-rays, including their ability to ionize gases and their high wavelengths. Group activities and evaluations will help reinforce key concepts.
