Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We’ll start by looking at motion itself. Then, we’ll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you’ll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

hi
thx alot!
Sweet!
Why after the first reflection of sound wave from the interface the sound waves continues to move further through the medium
wheather the change in density was not for the second wave
Wow ,your whole explanation of why ultrasound was used instead of audible sound due to its low wavelength leading to less diffraction was great.
wow !! thnx alot
I beileve in APEC
if that is the case using high f (which would result in low wave length) is better, does this mean the higher f the better image quality and people are using as high as possible of the f in practical?
What do you mean by interface? Thank you!
thanks a lot excellent video
EKG is what really kills:)))
Thanks for this video! Now I need to learn since I've bought Aloka. I bought it on Bimedis (Medical Equipment Marketplace) and I'm really happy for doing it:)
Don't I know THAT about patients. When I first became an EKG Technician, there were so many patients who DIDN'T want me giving them an EKG, because lots of them were worried about being electrocuted by it, it wasn't even funny.
This one guy gave me such a third degree of questioning that his girlfriend suddenly said "You act like she's fittin' to KILL you."
He mumbled a protest and she rolled her eyes.
I had to bite my tongue to keep from laughing.
