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 happens if laser source is used in newton rings?
Using a laser as the light source in Newton's rings experiment can produce more defined and intense interference patterns due to the laser's monochromatic and coherent nature. This can result in clearer and sharper rings, making it easier to measure and analyze them accurately compared to using a white light source.
How do you measure Nm?
Nm, or Newton-meters, can be measured using a torque wrench for fasteners or a torque sensor for other applications. The device will indicate the amount of force being applied in Newton-meters.

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?

What are the different types of ball bearing rings and their applications in mechanical engineering?
There are three main types of ball bearing rings: inner rings, outer rings, and cage rings. Inner rings are the part that fits onto the shaft, while outer rings fit into the housing. Cage rings hold the balls in place. These rings are used in various mechanical engineering applications to reduce friction and support rotating parts, such as in motors, pumps, and gearboxes.

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
Which lens should be used in newton rings short or long focal length?
A lens with a long focal length is typically used in the Newton's rings experiment. This is because a longer focal length helps produce a larger, more distinct interference pattern, making it easier to observe and measure the rings.
How do you replace o rings?
Their numerous applications where O rings are used, you need to be more specific. Car, Airplane, boat, or machinery
Is the distance between two adjacent bright ring and dark ring equal for the Newton's rings?
No, the distance between two adjacent bright and dark rings in Newton's rings pattern is not equal. The spacing between the rings decreases as we move from the center outwards, due to the curvature of the lens. This pattern is a result of the varying film thickness of air between the lens and the flat glass plate.
Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
