Transverse and Longitudinal Waves

100 - Transverse and Longitudinal Waves
In this video Paul Andersen compares and contrasts transverse and longitudinal waves. Waves carry energy through oscillations. In transverse waves the oscillations are perpendicular to the direction of the wave and in longitudinal they are parallel. Several examples and a simulation are included.

ESO. English: Artist’s Impression of How Type Ia Supernovae May Look like as Revealed by Spectro-Polarimetry Observations. The Outer Regions of the Blast Cloud Is Asymmetric, with Different Materials Found in “Clumps”, While the Inner Regions Are Smooth. Using Observations of 17 Supernovae Made over More than 10 Years with ESO’s Very Large Telescope and the McDonald Observatory’s Otto Struve Telescope, Astronomers Inferred the Shape and Structure of the Debris Cloud Thrown out from Type Ia Supernovae. Such Supernovae Are Thought to Be the Result of the Explosion of a Small and Dense Star - a White Dwarf - inside a Binary System. As Its Companion Continuously Spills Matter onto the White Dwarf, the White Dwarf Reaches a Critical Mass, Leading to a Fatal Instability and the Supernova. But What Sparks the Initial Explosion, and How the Blast Travels through the Star Have Long Been Thorny Issues. The Study Shows That the Outer Regions of the Blast Cloud Is Asymmetric, with Different Materials Found in “Clumps”, While the Inner Regions Are Smooth., November 30, 2006. www.eso.org/pub.... commons.wikimed....

Thanks for the video. I have a pretest in science about this soon and now I'm gonna do great on it.

[@esw5227]

wgu?

[@markhunterbrooks]

Fyi...I think the drawing of the polarizer in the diagram at 4:44 in the video should be turned 90 degrees. To me, it looks like the wave that made it through should have been blocked and the horizontal wave that was blocked should have made it through. Your thoughts?

[@Soloisbac]

I will give three goats for this work because you have helped me

[@dwallenwowden1607]

Thx for the A on my test

[@Chelsea-gs7qj]

Wow wonderful. Those animations really helped. Thank you so much!

[@TheLuminousOne]

i think transverse waves are not really up and down but in reality more circular...swinging in a circular spiral movement.

[@simonbera6823]

thanks sir its really help me to know waves better in easiest way

[@neilkannan7081]

this is sooooooo helpful and easy to understand!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@ajaykumarmandal4783]

Superb animated video

[@anush7386]

Sound will be heard from space huygen said there is a medium called ether which travel in sound waves and light

[@phantasyphotography3813]

Yeah, a wave from my understanding is what something does and you can't have a wave without something moving. If light is a wave then that means all around us is a medium that we're not aware of that allows electromagnetic waves exist.

[@haripriyavedala2892]

awesome cool explanation. Thanks

[@michaelryd6737]

EMF also requires a medium otherwise it can´t oscillate! Prove that I´m wrong...

[@tonlier7893]

Can you answer me this problem please If the time of 0.5 amplitude is 2 second calculate the time of complete oscillation or vibrating Reply quickly I'm intersted

[@carultch]

There isn't enough information, because we don't know the wave shape in this example. We also don't know the starting phase in the cycle, or which of the half-amplitude points we are given, within the cycle. Assuming it is sinusoidal, and that it starts in the phase of a sine wave, the half-amplitude occurs whenever sin(theta) = 0.5, and the full cycle occurs for every time theta equals an integer multiple of 360 degrees. When does sin(theta) = 0.5? The first answer is theta = 30 degrees, and the next answer is theta = 150 degrees. The general answer is 90 deg +/- 60 deg + n*360 deg. Most likely, the problem author had the first answer in mind, as the given half-amplitude point. This means it takes 1/12 of a cycle to move from the equilibrium state to the half-amplitude state, and therefore, the period of a full oscillation is 12*2 sec = 24 seconds.

Hi Mr Andersen, just wondering what program do you use to create your videos? Thank you :)

[@divyebhutani]

+Steph You can use Adobe After Effects or Sony Vegas.

[@Stephanie-rf4yj]

thank you

[@previsionssismisques7410]

How does a low-frequency mechanical (transverse) wave behave in a plasma ?

But if you go out in space where the medium is not thick enough (low density) you are not going to see any explosion from a nova, you wont even see the stars!

[@AbdullahQureshi1]

I don't get a WORD!

[@AliAhmed-bq3cq]

I am not getting longitudinal waves but I got transverse waves

[@michaelryd6737]

Any proof of your statement that emf waves does not need a medium? Have you tested that in some way or is it just a religion of yours and "The cult of Physics"...

[@carultch]

The fact that you can see the sun, is proof that an electromagnetic wave doesn't require a medium. If EM waves couldn't travel through empty space, you wouldn't ever see any astronomical body, and the sky would be pitch black all the time.

[@henryg9059]

WHAT THE FUCK IS A LONJITUDINAL WAVE

[@carultch]

A wave whose disturbance of the medium is is parallel and anti-parallel to the direction of propagation, rather than a wave whose disturbance of the medium is perpendicular. An example of a longitudinal wave, is sound.

[@lesliecalloway6057]

Who is watching this in the carona season

[@brodyhoops]

Have you ever been so smart that you miss spell longitudinal ( the beginning)

[@mutazahmed1336]

what

[@badbadkiddo]

Great. Except the earth is flat and electromagnetic waves certainly need a medium to go through like all waves, it's called the aether.

[@carultch]

Both of those are obsolete ideas.
