becaus thicknes of thin film is 0 and wavelenth is l so according to formula 2t-(l/2 ) destructive inteference will ocur and path difference is odd integral multiple of half of wavewavelenth

Why did Isaac Newton stay in a dark room for days on end?
Isaac Newton after looking at the Sun too long spoiled his eyesight so he stayed shut in a dark room to cure it. He was successful
Why newton ring are not equispaced?
no they become more closer as we go away from the rad
Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
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.
Did sir Isaac newton ever get in trouble as a teenager?
Yes. He was arrested for smuggling crack into a center.
Why is the center of the newton's ring is dark?
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.
Why ring start collapsing to the center when you use planoconcave lens in newton's ring?
don,t know
Why in newton's ring's experimental setup central ring is bright instead of dark?
Because the intensity is maximum at the centre. Therefore the central spot is bright and not dark.
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
How can we get a bright center in newton's ring experiment?
when dust particles come in contect of plano convex lence.
When was Newton Center - MBTA station - created?
Newton Center - MBTA station - was created in 1959.
Why center of newton ring is dark?
Newton's rings are created by the destructive and constructive interference between the light waves. Destructive is when one wave is at a crest (high point) and one is at a trough (low point) and they cancel each other out. Constructive is when both rays are at a crest or trough and they amplify each other. The dark areas (like the cenrte of the rings) are created by destructive interference.
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 do we observe the dark and bright colored frings in newton's ring?
the newton's rings are formed due to the phenomenon of thin film interference. here, the condition for constructive interference(the ring appearing bright) is that the optical path difference between interfering waves should be an integral multiple of the wavelength. the optical path difference is given by 2t-(l/2) if t is the thickness of the air film at that point and l is the wavelength of light. at the central point, the lens touches the surface so thickness t=0. thus the optical path difference is simply l/2, which is the condition for destructive interference, not constuctive interference. so the central spot has to always be dark.
Where is the Newton Town Library in Newton located?
The address of the Newton Town Library is: 51 South Center Street, Newton, 84327 9999
What will happen if a point source is used instead of extended source in Newton's ring experiment?
The rings may formd but the lack of intensity of light,the dark and light rings are not vissiable very well..
