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 else can I help you with?
Why cornu's fringes are hyperbolic and newtons rings are circular?
Cornu's fringes are hyperbolic because they are formed due to the interference of light waves that are not perfectly spherical when they meet at an angle. Newton's rings are circular because they are formed by the interference of light waves that are spherical in shape due to reflection between a flat glass surface and a convex lens.
Which light is used in newtons rings?
sodium light
Why isn't the Olympic rings square?
By definition, rings are circular. Therefore, if they were squares, they would not be rings!
What happens when a concave lens is placed in Newtons' rings experiment?
rings start collapsing to the centre
What is the name of worm which is brown and has circular rings on its body?
Earthworm.
Explain any one engineering application of interference due to thin films?
newtons rings
How are annual growth rings made?
by things growing annually in a circular fashion
What happened in newtons ring experiment if the glass plate is replaced by mirror?
if we use glass plate then ring's will be clear
Why newton rings are circular in shape?
Well, honey, Newton rings are circular in shape because they are formed due to the interference of light waves reflected between a flat surface and a convex lens. The circular shape is a result of the varying thickness of the air gap between the two surfaces, causing constructive and destructive interference patterns. So, in simpler terms, those rings are just a fancy dance of light waves showing off their interference skills in a circular fashion.
How can wire be used in the process of making rings?
Wire can be used in the process of making rings by shaping and bending it into a circular form to create the band of the ring.
What is the circular things to find how old a tree is?
They are called "rings". Each "ring" indicates a seasons growth. So by counting the rings the age of the tree is apparent.
To wind somthing into rings is?
to coil or rotate an object around a central axis in a circular or spiral shape.
