Question

Give any two uses of X-rays.

Hint:

X-rays are essential for medical imaging and cancer treatment, allowing for both diagnosis and targeted therapy.

Answer 1

Step 1: Understanding X-rays.
X-rays are a form of high-energy electromagnetic radiation. They have wavelengths between 0.01 and 10 nanometers, which are shorter than ultraviolet rays and longer than gamma rays. Because of their ability to penetrate solid objects, X-rays have many practical uses, particularly in the medical field.
Step 2: Two Uses of X-rays.
1. **Medical Imaging (X-ray Radiography):** X-rays are widely used for non-invasive imaging to diagnose various medical conditions. X-ray images allow doctors to see inside the body and examine bones, tissues, and organs. For example, X-rays are used to detect fractures, infections, tumors, and other abnormalities. 2. **Cancer Treatment (Radiotherapy):** X-rays are used in the treatment of cancer through a method known as radiotherapy. High-energy X-rays are directed at cancer cells to damage and kill them. This helps in shrinking tumors and treating cancerous growths. Step 3: Conclusion.
X-rays have vital medical applications, including imaging for diagnosis and treatment of diseases, especially cancer.
