Newton's Rings, a pattern of light and dark circles visible when a convex lens is placed, curved side down, on top of a flat piece of glass. The pattern was first observed by Sir Isaac Newton. The rings are caused by interference of light waves.
When a beam of light is directed downward onto the two pieces of glass, two overlapping beams of light are formed-one from light reflected by the lower surface of the curved glass and the other from light reflected by the upper surface of the flat glass. The light reflected from the flat glass travels farther than the light reflected from the curved glass. Depending on the distance between the two surfaces, light waves in the two beams may be in phase, reinforcing each other, or they may be out of phase, canceling each other out. Because the distances between the two reflecting surfaces increases with distance from the point where the lens and flat glass make contact, the areas where the waves are in phase and out of phase occur in concentric bands around the center of the lens.
If the beam of light directed at the two pieces of glass is monochromatic (of a single wavelength), the rings are thin circles of a single color. If white light (which consists of light of many different wavelengths) is used, the rings are fewer in number, but highly colored.
or you can just squint your eyes and watch into the sun and see those right inside your sight
Amazing video. Newton would enjoy it!
why light does not get reflected from the upper part of the plano convex lens? interference will happen or not???
Great Work Guys Easy to UNderstand
The Least Count is shown to be 0.001.
Isn't this wrong (or incomplete) without the unit (cm) ?
Dhaval Furia hey you are the one who is the best in sololearn surprised to see you....
Dhaval Furia as per your doubt i am with you
gr8 job guys !! (Y) impressed :)
It's a nice video but you can go little deeper in to the topic.
Nice and comprehensive... but you should have given the formula for calculation of radius of curvature
very interesting and easy to understand
thanks for uploading these videos
Thanks for the video. Helpful.
Great work!!!
very very helpful info!! thanks a million !
good one useful to revise before exams
sweet Nd simple helped me a lot

1st class
Excellent video.But you should've added subtitles. Your accent makes it hard to understand.
UA-cam should give users options of adding subs in their own languages. Such users can be given badges and special UA-cam options like themes etc. I would have written a thousand videos by now if there was such an option. I type like fire.
I feel proud to be a student of such a good university.. Amrita 👍🙏
sweet Nd simple helped me a lot
very interesting and easy to understand
