Sound Medium | Propagation of Sound | Why does sound travels faster in solids?

Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.

The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster the sound travels in a medium. The mathematical relationship is speed = (elasticity/density).

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids is not faster than in all liquids.

ONE ANOTHER DOUBT WHY TRANSVERSE WAVE CANNOT TRAVEL IN FLIUDS BUT LONGITUDINAL DOES

[chancebutler]

thank you! if im honest theres an ocean of science videos speaking english with strong accents that i find hard to understand or even listen to for a while. but wish i could. videos like yours show me its not the accent its the presentation and communication skills beyond just pronunciation :D

[macchen]

Reminds me of my school life
I didn't paid much attention though

[sanchitkalpande]

You are real teacher 😊 good teacher, keep it up Sir☺️

[nikitarawat]

SIR I HAVE A DOUBT PLZ REPLY ME AND CLEAR IT FOR WAVE PROPOGATION ELASTICITY OF MEDIUM IS NECESSARY...BUT WE KNOW THERE IS NO ELASTICITY IN FLUIDS SO WHY LONGITUDINAL WAVE TRAVEL IN FLUIDS...

[dynamicyt]

Sir, I had a doubt....
Molecules in solid are dense.
You said that sound travels faster in solids.
Now, in the textbook its given that velocity of sound is inversely proportional to density. So, if density is increased 4 times, then velocity reduces to half.
So, in solids the Velocity of sound should be less then as per this.
Please solve my doubt🙏

[_ridhimaagarwal_-a]

Is density directly proportional to the speed of sound in solids and inversely proportional to the speed of sound in gas

[SunilKumar-iejh]

What about density because I read somewhere that higher density means sound wave will travel slower?

[SEpian-HOje]

Why the sound travels faster in more denser material ?

[AHSAN-]

Sir kindly give concept about Newton's and laplace speed of sound

[shivanihr]

If speed of sound is constant (344m/s) then why do we calculate speed of sound for different wavelengths, with the formula ... speed of sound = frequency x wavelength. Because there are numericals given in kid's textbook to find out speed of sound with the given frequency and wavelength. Some websites on Google says speed of sound is uniform (344 m/s) and does not depend on frequency or wavelength, when the opposite is clearly given in the formula. Please explain.

[kaushalparuchuri]

Sir how can we prove that sound waves are LONGITUDINAL? what would happen if these are transverse in nature?

[ggarza]

If sound travels faster in solids, the distance it travels will be less than in gases?

[ranahumayun]

Thank you. Sir. the best stuff I have found on YouTube so far...

[MaverickWall]

So sound travels faster through rubber than water right?

[shashankj]

Wish you were there when I was studying engineering....

[AhmadShah-kdtg]

excellent teaching but only you should be increase your teaching thus we we'll be understand more

[VarenyaMaheshwari]

4:30 Then why in gases velocity of doing if inversely proportional to root of density?

[marcfruchtman]

Thanks for the video. I find it immensely annoying that scientists often use common terms with their opposite of their intended meanings. Everyone is brought up with the understanding that "elastic" means stretchable, yet, in physics, it is the exact opposite. LoL It is so frustrating.

[Agent_Pringles]

Thank you my physics teacher is no good at explaning this stuff
