This is the second time this week I was questioning a subject that I was studying and I googled online to aquire the answer and I was sent to you! I recognized your voice from the first study guide I followed this week. You are amazing and I agree with Lord Random you do give excellent explainations! You have just recieved a dedicated subscriber! Thank you so much!
I was browsing for a a solution on pure mathematics about the set where a function is continuous being a countable intersection of open sets. And, of course , found something nothing related: this video. Yet I learned something about geology! Thumbs up!
Either this video or German wikipedia is wrong...wikipedia says the waves took suprisingly long, this video says it took suprisingly short for the waves to be registered !
interesting. ive had to reaserch this for physics h/w. interesting that you said the waves travel faste in denser materials... wouldnt it be the other way around? speed of sound at sea levrl is apox 650-570 mph. Speed of sound at altitude is 740ish mph. I know waves can have higher aplitude is denser materials due to reifaction presure not being able to go below 0, but are you sure it travels faster?
Great video ! But I think there is a little mistake (or maybe an voluntary omission) : Isn't the crust under Zagreb about 55 km down because of the mountains, and not 35 km like mentionned (like an ordinary crust) ? =)
it is true that the speed of the wave will change, decrease to be precise, in a denser medium. but at the same time, the path of the wave will change too. will not the later, combined with the former, render an effect: 'the time taken for the wave to reach a certain point will be the same'. ?
I have a doubt. if the waves travelled through a denser material (mantle), thenthe dense material should offer more resistance to the waves slowing down its speed. But, here it is aid exactly the opposite that when the waves travelled through the dense material, its velocity increases. can someone explain me why and how this is possible.
It's not about shear force of waves. It's more about type of wave. S-waves propagate perpendicular to the direction of motion.-- like light (in wave form) while P wave motion is like sound wave. Now how does it matter? Well Solids like rock have shear strength that can hold them together, so wave move across them. But in liquid that's not the case. If you put a vertical plate in liquid and lift it then liquid won't rise, similar is case with S waves, ipso facto, nature of wave not force takes precedence here. - I hope I am able to clear the doubt.
You completely butchered his name, but it's okay :D
Pronounce the "j" like a "y" - Andriya. The "č" and "ć" are pronunced like "ch" as in chocolate.
Iksbrown so, it'll be pronounced as Mohorovichich?
ˌmō-hə-ˈrō-və-ˌchich-
You sir just earned a new subscriber.
Thank you for the great explanation

i literally just clicked this to learn how to say Mohorovicic thanks
It was totally butchered lol
perfect explanation! i'm having a class test tomorrow and this helped me so much
goodluck on your test tommorow
Will you also provide information why its more dence? You´ll have to go into mineralogy for that. I am looking forward to it.
Excellent explanation. Khan academy never disappoints.
YOU GUYS HELP ME LEARN MOREEE! THANKYOU
Superb great help
really helpful , thanks
We watched this in AP environmental science today because my teacher likes your enthusiastic description than what she would give.

hi, what did you use on this video?
Thank you.

Yeah because it’s easier to transfer energy from atom to atom when they’re closer together
EXCELENTE
Try to pronounce: Andriya Mohorovichich. Greetings from Croatia.
Great video ! But I think there is a little mistake (or maybe an voluntary omission) : Isn't the crust under Zagreb about 55 km down because of the mountains, and not 35 km like mentionned (like an ordinary crust) ? =)
@The95Alex Since when you use cyrillic in cro?;P
density does not increase wave velocity it slows it down look at the equations for p and s waves
You are awesome!
you're more awesome
hi exelent video. i have a M.C homework.... how to get the moho... can you giveme some advices.
I'm croatian and its hard to pronounce his name even for me :) In English it would be like Andrya Mohorovytsich
wow , thanks for letting me know
Mohoho wow !

The waves would get there faster than expected.
I have a doubt. if the waves travelled through a denser material (mantle), thenthe dense material should offer more resistance to the waves slowing down its speed. But, here it is aid exactly the opposite that when the waves travelled through the dense material, its velocity increases. can someone explain me why and how this is possible.
+Tessa Carlson Thnx I understand the geology of the earth a lot better now.
+Tessa Carlson One more doubt, so you mean to say that P-waves have that much amount of enough shear force that S-waves don't have?
It's not about shear force of waves. It's more about type of wave. S-waves propagate perpendicular to the direction of motion.-- like light (in wave form) while P wave motion is like sound wave.
Now how does it matter?

+Artin yes thank you so much. I even thank Khan Academy for this. My doubt is finally cleared.
wohoo croatia!
