- Sound Wave Experiments
In this video, we are going to look at the factors that influence the speed of sound and how to measure it.
We will look at sound waves in more detail in another video: Sound Waves
Sound travels at about 340m/s in air. At sea level. At 20 degrees celsius.
What does this tell us?
That temperature and air pressure affect the speed sound can travel through air. And this speed changes again for different mediums.
How is this possible? It’s all to do with particles. Let’s look at some evidence.
So sound travels at about 340 m/s in air.
In water, it travels at 1500 m/s, While in some solids sound can travel at up to 5000 m/s.
That’s incredibly fast compared to air!!
These differences are due to how particles are arranged in solids, liquids, and gases.

thank you . the teacher provided us with this link to learn
Thank you for this, this will be our next topic later in Physics and it is very interesting. Thanks a lot !
You are very welcome! 🙂
my physics textbook and other sources on the internet say that sound travels slower in denser mediums even though it does not make sense to me I am very confused. Does anyone know why there are different answers to this?
btw loved your video
I feel more comfort studying here than my TV channel 😀
Awesome sir
OMG!!! Thank you so much you helped me a lot thank you❤️
You are most welcome! Glad we could help!
Helped me get A+ in test :) BEST EXPELNATION
Amazing! Well done 🙌
You mean Explanation?!
If you released one side of a giant hollow coiled slinky from the back of a concord jet flying at the speed of sound, and for a brief moment one end of the slinky was traveling at the speed of sound and the other was traveling slower than the speed of sound, during which an audio signal was sent from the end traveling at the speed of sound towards the end traveling slower, would the wave be compressed or expanded at the point of signal measurement?
tysm much for this helped me with my science so much
You are most welcome! Glad it helped!
Does anyone know how I can make a sin graph of this (with data points) for a math project?
bro I swear this man is saving my grades
Very nice explaination
Thank you!
Me and my science teacher r wathing this rn thanku so much!!
Most welcome!
Best explanation!!!!!!!!!!!!!!!!!!!
Wow, thanks! 😃
Can a person feel the vibrations just after a bell rang ?(he doesn't know the bell rang...he arrives the place very fastly... though impractical...)
This video is very helpful for me ...💯
Glad to hear that!
it helped me realy
you are good
Glad it helped!
My physics teacher could never teach me as well in a whole term 😀
You are a good explainer hlad to see the video
Thank you! Glad you liked it!
Very nice explination ❤️
Thanks a lot 😊
AIR PRESSURE HAS NO EFFECT ON SOUND PER SE; changes in sound at higher altitude is due to lower temperature
Nice channel. New subscriber ❤️
Thanks for subbing! And welcome!
Noice
1:03 i don't understand. air is less dense. iit should travel more meter in air right?
Sound travels faster in a medium where molecules are tightly packed. That's why the speed of sound is higher in solids, and lower in liquids and gases.
@@fuseschool tnx a lot
Umm i really cant get the video "Wave equation" is it deleted
Try searching on www.fuseschool.org
You guys say that the pressure affects the rate at which sound travels but my teacher say that pressure doesn't affect the speed of sound the pressure gets cancelled out with the density??
You are quite right. For an ideal gas the speed of sound only depends on temperature (and the nature of the gas). Changing the pressure of air (it's not an ideal gas!) only slightly changes the speed that sound travels.
@@fuseschool okay I got it! Thanks
How is sound produced?
Sound is produced by vibrations in the air particles. Those air particles reach ur ear and vibrate ur ear drum later.
im just gonna have to say it. First
Luv that
