Propagation of Sound

Propagation of Sound: How Does Sound Travel? We explore Sound Waves and learn about transmission of Sound. Sound needs a medium to travel. Sound can travel in solids, liquids and gases! Sound Waves consist of a pattern of compression and rarefaction.

1. High pressure region - COMPRESSION
Low pressure - Rarefraction
2. Radio waves
3. Because in solids particles are closed to each other as compare as liquid and gas and sound travel faster in liquid than air because particles in liquid are much closer than gases .

Thanks 😊

[YoruShika-vhmd]

1. Compression and rarefaction
2. Light wave (since it can travel through vacuum no air )
3. sound travel much faster in solid because the particles in solid are compacted together leaving no gap which able the sound wave or vibration to travel quickly. Sound travel faster in liquid as well because liquid particle has a slight gap between particles and sound wave travel quick when liquid particles are close to each other. While in gas it is slower that liquid and solid, because gas has wider and chaotic gap or movement so therefore sound wave can only travel in few gas particles unless the temperature is warm.

1. Compression, Rarefaction
2. Electromagnetic wave. Because light travel as electromagnetic wave. Electromagnetic wave can even travel in vaccum.
3. In solid molecules are close enough.
In liquid, it's not close enough as solid.
In gas, they are far away than solid and liquid.

1) In a sound wave, the region of high pressure is called compression and the region of low pressure is called Rarefaction .2) Electromagnetic wave does not require any material median for their propagation . 3) Sound travel in solid is more faster than liquid and gas because in solid particles are more closely pack to each other as compare to liquid and gas and in liquid particles are not much far away as compare to gas, so thats why sound travel in liquid is faster than gas .

[giaiaiaia]

1) Region of high pressure is known as compression and the region of low pressure is known as rarefaction
2) Electromagnetic waves do not need a medium to travel and so, will be the same if used in vaccuum
3) This is because the molecules in solids are closer together than in liquids and molecules in liquids are closer together than in gases.

amazing explanation, thank you so much!!!

[sanbangtanarmy]

1. High pressure - Compression
Low pressure- Rarefaction
2. Electromagnetic waves(wave of light)
3. I don't know the exact answer but I think sound travel faster in solid because the particles of solid is close to each other as compared to liquid and gases

[SKIZZYDANIEL-uplf]

1. Compression and rarefaction
2. Electromagnetic wave
3. It's because in solid the particles are closer and fixed which vibrate around a fixed point why in liquid and gas thier molecule force are weak

Answers to the top 3 questions 10:45
1) Compression and rarefaction
2)Light wave
3)Because in solids the molecules are closer qnd hence they vibrate faster than any other medium .

[shakrullahfatihahayobami]

1.) The region of high pressure is called compression while the region of low pressure is called rarefaction
2.) The type of wave that doesn't require material medium is called electromagnetic wave
3.) wave travels faster in solids because the particles are closely packed together, for liquids they are slightly farther apart while the gas particles are farther apart

[namanbelwalsreviews]

ANSWERS:
1:Region of high pressure is the region of high compression of the sound waves in air &
the region of low pressure is the region of low compression of the sound wave in air.


2: Electromagnetic waves do not need any medium to travel like light.


3:In solids the particles are tightly packed so the sound waves can travel faster than a liquid
and in a liquid the particles are loosely packed but not as loose as air so the sound waves
travel more fast in liquid than in gases.



BY THE WAY SIR YOU ARE SUPER AMAZING AND I HAVE NO WORDS TO TELL YOU
ABOUT YOUR WORK FOR THIS VIDEO THANKS A LOT AND NEVER STOP BRINGING SUCH VIDEOS.

1: compression and rarefaction
2 :electromagnetic waves
3 : because the particles in solid are tight so they can transfer energy
Thankyou for such a nice explanation

[Batman-Avanish]

A fun as well as a great video, as you explain really good. Sir, the answers are:
Q1. A region of high pressure in a sound wave is a compression while a region of low pressure is a rarefaction.
Q2. An electromagnetic wave (Magnets work in a vacuum)
Q3. Because Solids have lesser intermolecular space than the other two states of matter, and so the sound waves can travel much faster.
Thank you!

1. In a sound wave the region of higher pressure and lower pressure are known as compressions and rarefraction. One compression and rarefaction come together to form a wave. Higher pressure refers to compressions and lower pressure refers to rarefaction.

2. Waves which do not need a medium for their propagation are known as electromagnetic waves. An example of an electromagnetic wave is light which can travel through a vacuum. Waves which do need a medium for their propagation are known as mechanical waves. Mechanical waves are categorised into transverse waves and longitudinal waves. Transverse waves are the waves in which particles vibrate perpendicular to their medium of propagation. Longitudinal waves are the waves in which particles vibrate parallel to their medium of propagation.

3. sound travels fastest in solids, then liquids, then gases. The particles of a solid are closely connected and when sound is produced in it then vibration can travel from one particle to another very quickly and efficiently since they are all so closely packed compared to vibrations travelling in liquid. In liquid particles are not very closely packed so sound cannot travel as efficiently and quickly as in solids as the vibrating particle needs to travel in search of another particle to transfer the vibration. Similar is the case between liquids and gases, liquids have particles more closely spaced together as compared to gases and thus can transfer vibrations quicker than gases.

[anujkumar-ybrz]

Q.1) High Pressure is Compression and Low pressure is Rarefaction
Q.2) non -mechanical waves
Q.3) molecules in solids are tightly packed so it easy for them to propogate, therefore it is faster .
Session was really amazing, loved ur teaching ❤️

[rithizx]

1) High Pressure: Compression
Low pressure : Rarefaction
2) Non- Mechanical wave
3) Because solids have High density compare to liquid compared to gas, therefore if the density is high the compression and rarefaction is more, hence speed of sound in solid> liquid> gas ❤

[Saimadance]

No doubts, teaching practically is ☺☺☺v. Good

[poulomilayek]

You explained it very well. Earlier I had gone through your lecture on concave and convex mirror . I was mesmerized. This time also, you have fulfilled my expectations. While I teach my daughter I look forward for your lecture. Keep it up. Manas Layek, Associate professor

[bhaskardebnath]

1. Compression and rarefaction respectively
2. light wave
3. In solids and liquids, the molecules of the matter are much closer than in air, which is a gas, so the sound doesn't travel much fast in air but faster in liquids and more faster in solids

[BizzBooms]

1 - a - Compression
b - Refraction

2 - Electromagnetic Waves

3 - Sound waves are just disturbed air particles. Sound waves travel faster in solids than in liquids and in air because the particles are tightly packed (closest in comparison to other types of particles resulting in sound particles to easily jump and travel between solids) If we compare it to liquids and gases, liquids have a medium distance between each of its particles and gases have the furthest distance between each of its particles. This distance makes it proceedingly difficult for sound waves to travel.
