why are Newton rings observed in a circuler pattern?
Consider how those patterns are typically produced--by putting a convex piece of glass over a flat plate. The curved surface has a spherical symmetry that leads to circular rings.FizixFreak said:why are Newton rings observed in a circuler pattern?
Newton Rings are a phenomenon of interference fringes that occur when a convex lens is placed on a flat glass surface. They are named after Sir Isaac Newton, who first observed them in the 1700s.
Newton Rings form in circular patterns because of the way light is reflected and transmitted through the convex lens and the flat glass surface. This creates a series of concentric circles of light and dark fringes due to the interference of light waves.
The formation of Newton Rings is caused by the interaction of light waves when they pass through a thin air gap between the convex lens and the flat glass surface. This creates a difference in the path length of the light waves, resulting in constructive and destructive interference patterns.
Yes, Newton Rings can also be seen in other situations where there is a thin air gap between two transparent surfaces, such as between two microscope slides or two soap bubbles. They can also be observed in anti-reflection coatings on lenses or in thin films of oil on water.
Newton Rings are neither harmful nor beneficial. They are simply a visual demonstration of the wave nature of light and can be used to study the properties of light and interference. In some cases, they can also be used as a tool for measuring the thickness of thin films or coatings.
