(d). Ultrasonic rays
Sonography, also known as ultrasound imaging, uses ultrasonic waves to create images of internal body structures. Ultrasonic waves are sound waves with frequencies higher than the upper audible limit of human hearing, typically above 20,000 Hz. These waves are used in medical imaging to visualize organs, tissues, and blood flow in real-time. The ultrasound machine emits these waves, which then bounce back from the internal structures and are detected by the machine, allowing the creation of images on a monitor.
