Newton's rings and interference

[huzaifa129]

Thanks,it is an easy method to see newton rings as my book tells to use plano convex lens,convex lens,plane glass plate and bla bla.:-))))))))))))

wtf

[FelipeZucchetti]

I mean, with two concave lenses??

[KakHazhar]

@FelipeZucchetti Yes exactly. Maybe I will in the future :)

[FelipeZucchetti]

Hello my friend, have you never tried with a "spherical" shape??

[KakHazhar]

@FelipeZucchetti Sorry for the late reply: Well I have tried but haven't filmed it :)

I could have imagined this simple experiment to see the Newton's rings. But I have not done it so far. So marvellous is this innovative demonstration of Newton's rings.-Professor Abraham Joseph

On the center of my touch screen cell phone screen, it have that stuff and it randomly formed one day, does anyone know what is is? Because i dont think its water since its in the shape of a perfect rectangle

[KakHazhar]

@vusiliyK Sorry man, don't know. All i know is that perfect rectangles are mostly man made :)

Maybe you could film it and upload it for us to see.

@vusiliyK

I had this on my phoneright before the screen started playing up. Then it stopped working completley. Nows its in for repair.

[looksintolasers]

@vusiliyK That's probably an interference pattern caused by a thin separation between two transparent layers in your screen. If that were true it'd be basically the same thing as in this video.

[projector72]

@vusiliyK dont worry about that. The screen of the cell phone is composed of two glasses. By touching it you kind of make some pressure as the guy in this video make that pressure by the point of pencil. Two glasses touch each other this stuff occurs, which is called newtons rings..

haha ... thanks ... ingenious i must say

i just wanted to see how Newton's Rings look like ... because my silly book wasnt good enough to give a clear diagram :)

[umer6945]

thanks ... that helped :)

[KakHazhar]

you're welcome :)

[KakHazhar]

Notice that I included the ruler at 1:00 so one can do measuring directly from this video.

For instance ,you can measure the distance between the two glasses just around the point of pressure (tip of the pen).

Ans:

It's in the order of micrometers that is

~ 0.001 millimeters.
