Wave Behaviour | Waves | Physics | FuseSchool

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 was almost crying not being able to understand the topic. Our teachers don't even help. Thank you ❤️❤️❤️🇵🇰

[shalinisawhney]

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.

[brandins]

I love how most people who've seen this video came from their teacher lmao

[ВоронМаусы]

As an optometry student, I find electromagnetic radiation (especially visible light) pretty fascinating

[Ravestor]

when 2 vids 4mins each on the internet teach you what the book wants to teach you in 7 lesson:

[RajosreeKarmakar]

Nothing to say...i am spellbound!!!
Thanks a lott for saving us ❤

[SULAIMANALBANDAR]

Bro thx this helped a lot i have a exam tmrw

[vndali]

its funny how almost everyone here is from online school lmao

[jaleelaasim]

@Fuse school - Global Education thanks for the video was really helpful

[nerd_yboi]

This video summarizes the topic very well. Thank you very much :D

[jaleelaasim]

A very helpful @Fuse school for the video

[thangboihangshing]

Please explain the behaviour of primary waves and secondary waves

[thisexists]

...I learned more from this video then I learned in 2 weeks on this subject

[Ovvkoz]

I like how it sounds as if "more bounce to the ounce" is playing in the background

[deannegoodfellow]

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.

Thanks a lot for your does sound waves bent away from the normal when they enter a denser

[saffansamnani]

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

[oreo]

this is so interesting thanks i have a test tommorow and i understandddd

[sarahpayne]

LIFE SAVER! THANK YOU SO MUCH. A GREAT HELP. XX

[glossomhyper]

oh that's why the sky and the ocean and the water is blue :D
:o ;-;
