#DidYouKnow: The speed of sound is around 767 miles per hour (1, 230 kilometres per hour). The loud noise you create by cracking a whip occurs because the tip is moving so fast it breaks the speed of sound!

Amazing explanation only in 4 mins hats off

[nivan]

I ‘’ Don’t ‘’ need to ‘’ memorise ‘’ this anymore 😂

[shekarnadimpalli]

I did not understand this subject for 2 years. But after your explanation i have understood this lesson in 1 minute. Thank u

[pragatiraval]

The best study channel
Now ever I need any explantion😇
I'll just type Don't Memories 😀😀
Thanks for such a brilliant explanation🙏🙏

[pavanmahoorker]

This video has simple explanation and great diagrams love this channel helps me a lot

[sonalmadaan]

I love this channel as it explains very well and clear the concepts in an amazing manner but the problem I go through is searching for the next correct video which is meant to be watched after the one which I am watching, as this channel explains a chapter in the videos which are the subparts of the chapter... So this must have a solution.. Otherwise I would say that it's the best channel for me I have ever seen.. 😍😍
Love it's way of explaining ♥️

[anushkakar]

Can you pls make a video on chapters of chemistry of class 9 🥺🥺🥺? It will really help me including other students confused with the chapters🥺

[aaliyasantlani]

This is the best channel it makes my physics concept easy and clear recommendable

[spmauryamaurya]

Don't memorise is the best video for understand I can understand this video very easily

[tinytan]

If we sing a song in sweet voice through a speaker it will do compression and rarefaction or it will work in medium

[srinidhinidhi]

Tq u mam i learnt it very fast.. by your explanation.🥰

[ramachandrajoshi]

Actually the channel name is correct to your video. U explain really like it. The concept is understood in this video.Not only this but in all videos. Tq for saving for all the students from by hearting....U really explain awesome

[mwahiduzzamanabegh]

Great video, thnx mam for clearing the doubts.
Life is a teacher, which teaches how to live.
Life is a teacher, which teaches how to win.
Life is a teacher, which teaches how to laugh.

Thanks a lot to don't memories....because whenever I didn't understand something I come to you.

[ratneshwarroy]

This topic is in our class 8 sound chapter i understood it clearly cause of you ..THANK YOU!!

[uzmakhan]

I am fan of don't memories..so good job cary on

[sarthakmotwani]

Thanks a lot... I finally got the concept ... :)

Sound travels through a medium by creating disturbances that cause compression and rarefaction of particles in the medium.

[00:00] Sound travels through a medium by setting the particles of the medium into vibration.

[00:33] Sound travels through a medium by displacing particles and causing them to collide with adjacent particles.

[01:04] Sound waves are disturbances produced by a source traveling in a medium.

[01:35] The tuning fork produces sound through vibrations

[02:05] Sound is created by compressing and decompressing air particles.

[02:35] Motion of 155.19 - 160.41 creates a low pressure region and disturbances.

[03:08] Sound waves travel in the form of compressions and rarefactions.

[03:41] A mechanical wave requires a material medium to travel.



Detailed Summary for [Propagation of Sound | Don't Memorise]

[00:00] Sound travels through a medium by setting the particles of the medium into vibration.
- Sound requires a medium for propagation.
- The vibrations of an object cause the particles of the medium to vibrate.

[00:33] Sound travels through a medium by displacing particles and causing them to collide with adjacent particles.
- Particles near the source get displaced.
- Collisions between particles cause adjacent particles to also get displaced.
- This process continues until the sound reaches its destination.

[01:04] Sound waves are disturbances produced by a source traveling in a medium.
- The particles of the medium do not travel from the source to the human ear, they merely oscillate from their mean positions.
- The disturbance created by the vibrating object in the medium is what we call a sound wave.
- The appearance of this disturbance can be studied with the help of a tuning fork.

[01:35] The tuning fork produces sound through vibrations
- The tuning fork is made up of steel
- The prongs of the tuning fork vibrate to produce sound

[02:05] Sound is created by compressing and decompressing air particles.
- When an object is away from its mean position, it pushes and compresses the air particles around it.
- This compression creates a high pressure region known as compression.
- The compression travels through the medium as a disturbance, with high density and particles close to each other.
- When the object moves towards its mean position, the pressure on the right side decreases continuously.

[02:35] Motion of 155.19 - 160.41 creates a low pressure region and disturbances.
- Vera faction is observed at 160.41 - 166.41.
- Compression and rarefaction travel as disturbances in the medium.
- Disturbances are characterized by less density of particles and vibrations.

[03:08] Sound waves travel in the form of compressions and rarefactions.
- Different sources of sound generate sound waves in the same way.
- The sound waves are also known as mechanical waves.

[03:41] A mechanical wave requires a material medium to travel.
- Sound waves also require a medium to travel.
- Vacuum cannot support the travel of sound waves.

Amazing explanation but please make video of each chapter of 11th and 12th of Ncert
