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 is the edge formed by two surfaces meeting each other called?
Boundary
What boundary is formed when magma rises to the surface and new crust is formed?
divergent
Why are metamorphic rocks not common on Earth's surface?
They are formed under the earth's surface.
What surface feature is formed where two plates meet?
The surface feature formed when two plates meet is known as a fault. In some cases mountains can also be formed when two plates collide.
A small angled surface formed between two surfaces?
a square
You are a geometric solid you have two surfaces One of your surfaces is formed by a circle The other surface is curved What are you?
a coneType your answer here...
Why do suction cup stick to wet surfaces better than dry surfaces?
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.
what is a You are a geometric solid you have two surfaces One of your surfaces is formed by a circle The other surface is curved What are you?
I may be the upper or lower half of any oblate or prolate spheroid.You'll never know.bwahahaha
How is friction formed?
Scientists are not completely sure what causes friction; however, it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.
Why are mirror images perfect?
No ! The images formed by a mirror are not perfect !!The finest images are those formed by a right angled PRISM . However the rays from the object need to fall perpendicularly on prism's surface . Thus for convenience mirrors are used .
Which types of triangles can be formed by taking the cross-section of a cube?
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
What is the different between the incisal ridge and incisal edge?
it might be good at this point to differentiate between the two term incisal ridge and incisal edge the incisal ridge is that portion of the crown which makes up the complete incisal portion. when and incisor is newly erupted , the incisal portion is rounded and merges with the mesioincisal and distoincisal angles and the labial and lingual surfaces. this ridge portion of the crown is called the incisal ridge. the term edge implies an angle formed bye the margin of two flat surfaces. therefore an incisal edge does not exist on an incisal until occlusal wear has created a flatten surface linguincisally, which surface forms an angle with a labial surface. the incisal edge is formed by the junction of the linguincisal surface, sometimes called the incisal surface, and the labial surface.

In newton's ring how does interference occur?
Newton'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.
What is the difference between a island and a cay?
a low elavation of land formed from the surface of coral reefs
How are plain surface formed?
plain surface is formed by rocks and minerals making a flat surface. that is the answer to your question.
What do you mean by friction?
When two surfaces rub against each other, friction is formed. It is the force resisting the relative motion between fluid layers, solid surfaces and material elements that are sliding against each other.
