What are the applications of newton rings?
Newton's rings are commonly used in the measurement of surface flatness in optics, such as lenses or mirrors. They can also be utilized in interferometry to determine small variations in thickness or refractive index of transparent materials. Additionally, Newton's rings can be used in quality control processes to check the uniformity of thin films or coatings.
Why is sodium light used instead of white ordinary light in newton's rings?
Newton's rings are caused by interference of light waves. When monochromatic light is used, then newton's rings are alternately dark and bright .When white light is used then a few coloured rings are visible.After that due to overlapping of rings of different colours , the rings cannot be viewed. The different colored rings are obtained because of different wavelength of colors. the order of colors depend on order of ring.
Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
What is the cause of Newton's rings?
When a plano-convex lens with its convex surface is placed on a plane glass sheet, an air film of gradually increasing thickness outward is formed between the lens and the sheet. The thickness of film at the point of contact is zero. If monochromatic light is allowed to fall normally on the lens, and the film is viewed in reflected light, alternate bright and dark concentric rings are seen around the point of contact. These rings were first discovered by Newton, that's why they are called NEWTON'S RINGS .experimental setupPattern of Newton's RingWHY NEWTON'S RINGS ARE FORMEDNewton's rings are formed due to interference between the light waves reflected from the top and bottom surfaces of the air film formed between the lens and glass sheet. EXPLANATIONThe phenomenon of the formation of theNewton's rings can be explained on the basis of wave theory of light.An air film of varying thickness is formed between the lens and the glass sheet.When a light ray is incident on the upper surface of the lens, it is reflected as well as refracted.When the refracted ray strikes the glass sheet, it undergo a phase change of 180O on reflection.Interference occurs between the two waves which interfere constructively if path difference between them is (m+1/2)land destructively if path difference between them is mlproducing alternate bright and dark rings.
What reference source would you use to find info about the rings of Saturn?
in a almanac!
What will happen if a point source is used instead of extended source in Newton's ring experiment?
The rings may formd but the lack of intensity of light,the dark and light rings are not vissiable very well..
How measure angle of biprism using newton's ring?
Newton's rings are a phenomenon of interference patterns created between a flat surface and a spherical surface. The interference patterns provided by a biprism aren't rings like newton's rings, but the spacing between them can help provide some measurement to the near-180 degree angle of the biprism.
What happens if you replace glass plate with plane mirror in newton ring experiment?
If you replace the glass plate with a plane mirror in the Newton's rings experiment, interference fringes will not be observed. The formation of Newton's rings depends on the light reflecting off the two surfaces of the air film between the glass plate and the lens, creating interference patterns. However, the mirror does not create the necessary conditions for interference to occur.

What are the laws made by newton?
Laws of motion law of gravitation law of cooling spectrum corpuscular theory newton's rings
Why are rings circular in newtons rings?
Since a plano-convex lens is being used in Newton's Rings .. that's why=the fringes are seen circular from above, on the glass plate.=
What happens if a cell phone rings in your pocket?

What happens to froddo?
You have to read The Lord of The Rings. Everything that happens to him happens in that book.
What is the use of the newton's rings?
newtons ring is formed due to the consequtive circle of different radius of bright and dark in which the centre is dark
What happens when a silver plate is used in newton's rings experiment?
When a silver plate is used in Newton's rings experiment, interference fringes are observed due to variations in the thickness of the air gap between the plate and a plano-convex lens placed on a flat glass surface. This is because of the reflection of light waves from both surfaces, leading to constructive and destructive interference patterns that form the rings. By analyzing the pattern of these rings, one can determine the thickness of the air gap at different points.
