At the point of contact the lens and the glass plate, the thickness of the film is effectively zero but due to reflection at the lower surface of air film from denser medium, an additional path difference of Lemda/2 is introduced. consequently, the centre of newton ring is dark due to destructive interference.

What is Radius of curvature in newtons rings?
Radius of curvature in Newton's rings is the radius of the curvature of the wavefront at the point where interference fringes are observed. It is calculated by measuring the diameter of the nth dark ring and using the formula R = (n * λ * D) / (2 * δ), where R is the radius of curvature, n is the order of the ring, λ is the wavelength of light, D is the distance between the lens and the glass plate, and δ is the diameter of the nth dark ring.
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.
What is the relationship between gravity and newtons?
Gravity is a force of attraction between two objects with mass, and it is commonly measured in newtons (N). Newtons are the unit used to quantify force, and in the case of gravity, it represents the amount of force with which an object is pulled towards the center of the Earth or any other massive body.
What is the difference in 200 newtons and 20 newtons?
The difference between 200 newtons and 20 newtons is 180 newtons.
What is the abbreviation of newtons?
The abbreviation for newtons is N.
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 is a Ring with no center?
I think a ring with no center is a sphere......?????...yes?..no?
Does the center of gravity always lies on the body?
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
Why does Ryou Bakura have a dark side?
Cause he has the millennium ring, and the ring has a dark spirit that lives in bakura's body.
What is Radius of curvature in newtons rings?
Radius of curvature in Newton's rings is the radius of the curvature of the wavefront at the point where interference fringes are observed. It is calculated by measuring the diameter of the nth dark ring and using the formula R = (n * λ * D) / (2 * δ), where R is the radius of curvature, n is the order of the ring, λ is the wavelength of light, D is the distance between the lens and the glass plate, and δ is the diameter of the nth dark ring.
Why is it hard to steer a bike whilst holding the center?
If you exert a force of 100 newtons , and your hands are 10cm (0.1m) from the pivot(the center of the handlebars, the formula is force(100)xPerpendicular distance (0.1) the force would be 10 newtons , but if you increased the distance your hands are from the center (e.g. to 50cm away) the force would be 50 newtons , So, the greater the distance from the center , the greater the turning force (moment).
Does the centre of gravity always lie inside the body?
No. The classic counterexample is the torus (ring-shape); the center of gravity is in the geometric center of the ring, which is NOT part of the ring.
What is the best Beyblade ring?
dark bulls energy ring is the best ever
How do you find the center of gravity of an object?
POKE a hole in the middle of Isaa Newtons head.
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
What was the problem in lord of the ring?
Sauron and the other creatures on the dark side try to get the ring.
What happen when planoconcave lens is placed in newtons ring explain in detail?
dont know plz you tell me the answer in detail
