How does an ultra sound works? help?:-)
Hi, im trying to revise the ultrasound topic in physics unit 3 and it says in the revision guide that " when a wave passes from one medium into another, some of the wave is reflected off the boundary between the two media and some is transmitted and refracted. This is partial reflection."
Despite the long explanation, i genuinely dont get what partial reflection is and what does it mean when it says that some of the wave is refracted off the boundary?

Have you done any optics yet? Same words with the same meanings in this context.
Reflection is when a wave bounces off a boundry e.g. At a swimming pool when you can reflections of the lights in the ceiling bouncing off the water surface.
Refraction is when the wave crosses the boundry and keeps going on the other side, e.g. being able to see the tiles on the bottom of a swimming pool when you're stood at the side.
The reflection is partial when only of the wave energy is bounced off.
