Why are rings circular in newtons rings?
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 is Radius of curvature in newtons rings?
The answer is 127.35cm
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.
What happens when a concave lens is placed in Newtons' rings experiment?
rings start collapsing to the centre
Why all rings in newtons rings are not equispaced?
outer rings are spaced more closely than the inner ones.Because slope of lens increases outward,separation of rings get smaller for the outer rings.
What is the wave length of the light used newtons ring?
Any wavelength of light can be used. Natural light, the white light we receive from the Sun, is a mixture of waves with wavelengths between about 350 and 700 nm.
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
Explain any one engineering application of interference due to thin films?
newtons rings
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..
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 is an extended source used in newtons ring experiment?
extende source is required to get nearly parallel rays of light
How old is a tree with 10 light rings and 10 dark rings?
ten years rings of same colour are years, whether light or dark
