How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal.
Transmission, reflection, refraction, diffraction, absorption and scattering are all typical wave behaviours.
Reflection is when waves bounce off an object. Sound waves are reflected by hard, flat surfaces and is why we get echoes.
You hear a delay between the original sound and the echo, because the echoed sound waves have to travel twice as far to reach your ears.
Smooth surfaces, like glass and polished metal, reflect light in a regular way, so a reflection can be seen. Like a mirror, or seeing your face in a calm pond.
Transmission is when waves keep travelling in the same direction through an object. Like light through a window.
Absorption and reflection often go hand in hand for light waves.
White light contains each wavelength - so all the colours of visible light. The colour of an object depends on which wavelengths of light it absorbs and which it reflects.
[...]
Sometimes waves depart from the expected path, and spread out in multiple directions. This is known as scattering.

I love how most people who've seen this video came from their teacher lmao
Not I, lol
I was almost crying not being able to understand the topic. Our teachers don't even help. Thank you ❤️❤️❤️🇵🇰
You're very welcome ❤️
@@fuseschool ❤️❤️
its funny how almost everyone here is from online school lmao
yea lmao
when 2 vids 4mins each on the internet teach you what the book wants to teach you in 7 lesson:
Facts
@HTMMALK PewDiepie Floor gang?
hey guys if you had to watch this for school and need definitions but you're bored and want easy answers, read full description. your welcome.
As an optometry student, I find electromagnetic radiation (especially visible light) pretty fascinating
A very helpful video..........Thanks @Fuse school for the video
Thank you, extremely helpful.
Glad to hear it!
Very cool short video
Please explain the behaviour of primary waves and secondary waves
@Fuse school - Global Education thanks for the video ......it was really helpful
@Jaleela Asim thank you! Glad it was helpful!
This video summarizes the topic very well. Thank you very much :D
Glad it was helpful!
@@fuseschool It was indeed! Thanks for all.
u saved us💕
Sooo informative video
Glad you think so!
Get this top comment because why not
I like how it sounds as if "more bounce to the ounce" is playing in the background
whats the song in the backround??
Thanks this really helped me! :)
No problem! Glad it helped!
Thanks a lot for your reply......So does sound waves bent away from the normal when they enter a denser medium?????
Correct!
LIFE SAVER! THANK YOU SO MUCH. A GREAT HELP. XX
Glad it helped!
Very informative
Glad you think so! 😉
super helpful 😃
Awesome! Glad it was helpful!
technologies that use the wave behavior of waves???
...I learned more from this video then I learned in 2 weeks on this subject
Glad to hear that!
Samee
Thank you, God bless you 💕
this is so interesting !!!!! thanks i have a test tommorow and i understandddd
Hope it went well!
Exams tmrw ! U saved me ❤️
Happy to help! Good luck tomorrow 🙌
thanks!
No problem!
Thank you FuseSchool, very cool!
Glad you liked it!
Oh yeah yeah
oh that's why the sky and the ocean and the water is blue :D
:o ;-;
The ocean is blue because it absorbs the color red and reflects the opposite color which is blue. If you don't know where the red comes from, than look at the video again!
Plz upload a video on refraction through lens.
Tq
Can Someone explain why light spreads/diffracts and dont goes like a beam ? 3:10
Please.
still need help
Same TvT
Very helpful for those studying physics!
Glad you think so!
I have learned
I have not
Both Sound and Light Waves enter into a medium and get refracted. But why when a sound wave enters into a denser medium, it travels faster while on the other hand the light & other transverse wave travel slower. Also do sound wave bent away from the normal when they enter into a denser medium(for their speed increases), unlike light waves?????
Interesting question. Remember that sound requires a physical medium to propagate, so normally the denser the medium the faster and easier the sound travels, meaning that it cannot travel in a vacuum. The opposite is true of electromagnetic waves, such as light, which require no physical medium to propagate, so the more matter blocking their path the slower they travel. When waves enter a medium that slows them down they get bent towards the normal - think of how you would walk diagonally across a field with a muddy strip across the middle. You'd try to walk as much as possible on the grass and cut steeply (bending towards the normal) to cross (slowly) the muddy bit then bending away from the normal again to finish your diagonal path at your normal speed.
@@fuseschool does sound waves bent away from the normal when they enter a denser medium?????
Yes, they do.
@@fuseschool thanks😊
I observe folks out there having difficulties as well as at this time taking power over over their very own matters, you feel that you are not about to be able to finally become empowered if you happen to be not wanting to bring about the choice that sets you totally free. The thing is that the selections we make are positively or perhaps adversely augmenting our behaviour and so our existence.
First comment ,,,,, helpful thanks
Glad it helped!
Curiously waiting for your reply 🤒🤒🤒
bro who else had to watch this video bc your teacher made you
Lijep video!
Let’s go first
Umm can you make a detailed video about reflection and refraction and discuss their laws....Like for refraction the law is snell law,etc...
Ye
what is the name of the music?
Check out the end of the video, it should be there 😉
could you look at the questions i asked on reproduction in the sexual reproduction video please?
5² 👀
my teacher forced me to watch this
bless
light and waves are simuler
Music reminds me memes
who else has this for class?
here for school😰
Who has to watch this for Astronomy?
hello mate
This is a video
Yes!
First
Why i don't see any comment?
Sorry, updating comments section is going very slowly at the moment :(
k
me
i was here lmao - yara f
No cap i hardly watched this bs
school made me
Exam tomorrow 😭
Hope it goes well! 🤞
Same
Tomorrow I have one and I have no idea
my teacher made me watch it, it wasn't really helpfull
Its just wiggly air
lol, schience?
j
h
No comment?
i disliked this because my teacher gave me this :>
