One of the important areas of scientific study in which ultrasonics has had an enormous impact iscavitation. When water isboiled, bubbles form at the bottom of the container, rise in the water, and then collapse, leading to the sound of the boiling water. The boiling process and the resulti...
In the process, we hope to ignite their curiosity, inspire their interest in physics and STEM subjects, and help them develop a deeper appreciation for the wonders of the world around them. We will cover topics such as how to make a sound, the anatomy and functioning of the human ear, ...
MALE STUDENT: Are you going to talk at all about the difference between radio waves and sound waves?MALE PROFESSOR: Um, OK. That might be a good place to start, actually. Sound waves are mechanical in nature, right? Ah, they can only originate and spread in places where there is some...
