when dust particles come in contect of plano convex lence.
if we use glass plate then ring's will be clear
The condition for constructive interference in thin filmis,m = 0,1,2,....From equation (1) putting the value of t in the above equation we get,since n = 1 for air filmorFor first bright ring, m = 0For second bright ring, m = 1For third bright ring, m = 2Similarly, for Nth bright ring,m = N - 1Radius for dark ringThe condition for destructive interference in thin filmis,2tn = mλ m = 0,1,2,....By putting the value of t, we get,For air n = 1For i.e. point of contact.
newtons ring is formed due to the consequtive circle of different radius of bright and dark in which the centre is dark
Radius of rings is directly proportional to the square root of the radius of curvature. Thin lens would have larger radius of curvature and hence the option
An extended source is used in Newton's ring experiment to ensure uniform illumination across the entire surface of the plano-convex lens. This uniform illumination helps in producing a clear and distinct pattern of interference fringes, making it easier to measure the diameter of the rings accurately. Additionally, using an extended source reduces the effects of coherence length and ensures a consistent interference pattern, improving the reliability and precision of the experimental results.
if we use glass plate then ring's will be clear
An extended source is used in the Newton's ring experiment to ensure that the light incident on the glass plate is coherent and uniform. This helps to produce clear and sharp interference fringes, which are essential for accurate measurements of the radius of curvature of the lens and the wavelength of light.
Ring of Bright Water was created in 1969-01.
The duration of Ring of Bright Water is 1.78 hours.
Ring of Bright Water is an autobiographical book by Gavin Maxwell

I think a ring with no center is a sphere......?????...yes?..no?
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
Saturn
Neptune have 3 bright ring's scienist said.

a halation ring is the imaginary ring that surrounds a bright object when you take a picture of it
