Question

question 1
doctors use which type of em wave to destroy cancer cells in radiation therapy?
gamma rays and x rays
microwaves
infrared radiation
visible light and x rays

Explanation:

Gamma rays and X - rays have high energy. In radiation therapy, this high energy can be used to damage the DNA of cancer cells, preventing them from dividing and growing. Microwaves are mainly used for heating (e.g., in microwave ovens). Infrared radiation is associated with heat transfer (e.g., thermal imaging). Visible light has much lower energy compared to what is needed for destroying cancer cells effectively in radiation therapy.

Answer:

Gamma rays and X rays
