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.
What are the applications of newton rings?
You can use newton's rings to measure the refractive index of a substance placed beneath the same lens I'm sure there must be more though .......
Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
Can cobalt wedding rings be resized?
Cobalt wedding rings can be resized without damage. The jeweler will heat it to an extreme temperature and make it larger or smaller to fit the finger. Cobalt is popular for rings due to its affordability and durability.
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 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..
What happens when a silver plate is used in newton's rings experiment?
fringes will shift because path differnce of wavelength/2 will remove.

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 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 is the mechanism of newton frings?
Newton's rings are interference patterns, caused by the varying distance between the two pieces of glass.Newton's rings are interference patterns, caused by the varying distance between the two pieces of glass.Newton's rings are interference patterns, caused by the varying distance between the two pieces of glass.Newton's rings are interference patterns, caused by the varying distance between the two pieces of glass.
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 if a cell phone rings in your pocket?
Nothing it just rings
What happens to froddo?
You have to read The Lord of The Rings. Everything that happens to him happens in that book.
Can a tungsten ring be engraved?
Tungsten rings can be engraved with a special laser engraver. Do not use a standard one as it will look bad and just ding up the ring. Expect to pay $25 - $50 for a laser engraving. --------------------------------------------------------------------------------------------------- Yes the laser engrave on tungsten ring should be a light grey color . The laser won't damage the ring surface and after laser engraved, rings will still with a smooth face. Most tungsten jewelry supplier charge the laser engrave but some of them are not like tocoy.
