Practical Applications
## Physics in the Hospital
Imaging techniques like X-rays, MRI, and ultrasound rely on physics to see inside the body without surgery.
- **X-rays**: Use high-energy electromagnetic waves to image bones.
- **MRI**: Uses strong magnetic fields and radio waves to visualize soft tissues.
- **Ultrasound**: Sends sound waves to create images of organs and babies.
Physics helps doctors diagnose diseases, guide surgeries, and even monitor heartbeats!
Examples
- A doctor uses ultrasound to monitor a pregnancy.
- An MRI scan reveals a torn ligament in a knee.
