Question

Describe the properties of sound waves that make ultrasounds possible.

Answer 1

ok, so sound waves, are what we commonly refer to as sound, and is self explanitory.

ultrasound waves are are very similar to sound except they are in a frequency range that our ears can't hear.

for example, you've heard that dogs can hear sounds that we can't. this is a similar idea to sound waves and ultrasound waves. to us we can't hear it, so that particular sound would be like an ultra sound wave to us, but to a dog, they can hear it, so to them it's a sound wave.

make sense?

ultrasound is also used in seeing images of a baby while inside the mother. the sound is directed towards the fetus, and the sounds will bounce back off the fetus, making a shape so to speak.

Answer 2

you know, i think i failed to answer your question.
the properties of sound waves that makes ultrasound possible is the frequency, or cycles per second.
we can hear to a frequency rate of 20 kHz. any frequency higher than that is an ultrasound

Answer 3

so the property is frequency

Answer 4

thank you! your answers are both correct and they actually guided me to get the official answer. However, I still need to focus on how reflecting and transmitting energy of sound waves makes it possible.

Answer 5

Well, I understand that sound travels through any material by vibrating that material, so in air, sound the molecules of the air vibrate against each other.
as for reflecting, i believe sound waves reflect off surfaces the same as a ball on a pool table off the side bumper. the angle made from the ball going into the bumper is the same angle the ball leaves the bumper.

Answer 6

thank you so much! you've been so helpful!

Answer 7

you bet!
