How does ultrasound work? | Jacques S. Abramowicz

The video explains how bats use ultrasound to navigate in the dark by emitting high-frequency sound waves that bounce off surfaces, creating echoes that help them map their environment. This concept inspired the development of sonar technology during World War I and later medical ultrasound imaging. Medical ultrasound is a non-invasive technique used to visualize internal organs, particularly in fetal imaging. It uses high-frequency sound waves to create detailed images without harmful side effects. The video also highlights the advantages of ultrasound over other imaging technologies, emphasizing its safety and portability.
