I was reading Digital signal processing and there I came across the term 'aliasing'. The author wrote aliasing is not always a pitfall to avoid, but there are applications that exploit it too. The stroboscope is one for example. Then I came to youtube to search what stroboscope is, and amazingly I understood what the author meant. Thanks for this great explanation.

superb explanation, thanks :)

This video is very helpful and the explanation is very easy to understand. The demonstration is very clear and to the point.

[@beforeafter4369]

practical explanations are always easier to understand...thnks for the video😁

[@jyotindroadhikarimayum]

just came to know about this after a stroboscope in ENT chapter…that’s a really cool concept 😊

Thank you !

[@nurlatifahmohdnor8939]

We can directly observe sun with our eyes. We have eye-lids that can flip open and close. So the shape of the sun is observed as sharp-image circle.

pA
pEnd is verb.
pOnd is noun.
pI
pU

[@nurlatifahmohdnor8939]

pEnd = [C15: from L pendere (italic) to hang] page 869.
pOnd = a pOOl of still water, Often artificially created. [C13: pOnde (italic) enclOsure] page 912.

Lyle is the white line on the black disc

[@joshsticko]

What if it was spinning 3 times and you doubled/halves the frequency of the stroboscope? Then there would be 2 opposite lines as well?

[@bogtheforest]

Seems to me if you halved the frequency you'd get a flash every six rotations, so you would still see the same one line. If you doubled it you would have two lines opposite since you would have one flash at the beginning and then another half way through the second rotation

[@AdiSonu222]

thank you sir
my teachers are doing it wrong all the time

[@nurlatifahmohdnor8939]

Do you have a simple experiment about wave?

[@nurlatifahmohdnor8939]

Electron moving, generate 'untouchable' magnetic field that creates F.
F = force
That is proportional with P.
Ok
Force resulted fr. magnetic field has vector. Ki-ri, ka-nan, ha-da-pan, be-la-kang...
In direction a
b
c
d
z
I mean not just x, y, z like we use to draw on paper (2D) or other people 'draw' (>2D)

[@nurlatifahmohdnor8939]

Can light be freezed?

[@nurlatifahmohdnor8939]

Intensity = ?
Ke-amat-an ? (Exact word)
To-na (for light observed by naked eyes. Colour from reflected light fr. chemistry compound is different from colour that comes fr. electrified liquid crystal)
Our eyes love x, prefer x, etc.
Up to you.
Good videoclip. Terima kasih.

[@bronzejourney5784]

Can a stroboscope be used to measure high speed rotation such as a 4 inch ring spinning at 7200 rpm?

[@muhammadmuzammilnawaz8253]

+Todd Pinney yes it can be used

[@kumarravi2963]

waste of time...90% of the time u were teaching school kids...just make the line stable and end the video

[@0xCAFEF00D]

I'm pretty sure this is for education though. Kids need to know what frequencies are about.

If u don't have the capacity to understand,then don't blame his video.
