A lens with a long focal length is typically used in the Newton's rings experiment. This is because a longer focal length helps produce a larger, more distinct interference pattern, making it easier to observe and measure the rings.
Newton's rings are a phenomenon of interference patterns created between a flat surface and a spherical surface. The interference patterns provided by a biprism aren't rings like newton's rings, but the spacing between them can help provide some measurement to the near-180 degree angle of the biprism.
If a plane mirror is used in place of a glass sheet in the Newton's rings experiment, interference patterns will not be observed. The glass sheet is crucial in creating a thin air film that causes interference patterns to form. Without the glass sheet, there will not be a variation in the path length of light, leading to the absence of 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.
Blue light travels slower in glass then red and so has a higher index of refraction. That results in a shorter focal length. Search Chromatic aberration in Wikipedia.org, "The World's Encyclopedia"
Oh, my friend, Newton rings are fascinating! When you see them in transmitted light, it's like nature's way of showing you beautiful patterns. Those rings appear due to interference between the light waves reflecting off the two surfaces. Embrace those rings as a reminder of the wonders of light and color around us.
Using a laser as the light source in Newton's rings experiment can produce more defined and intense interference patterns due to the laser's monochromatic and coherent nature. This can result in clearer and sharper rings, making it easier to measure and analyze them accurately compared to using a white light source.

Newton's rings are commonly used in the measurement of surface flatness in optics, such as lenses or mirrors. They can also be utilized in interferometry to determine small variations in thickness or refractive index of transparent materials. Additionally, Newton's rings can be used in quality control processes to check the uniformity of thin films or coatings.

Propably because it would be very difficult to measure the difference between the rings' diameters.
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.=

How do calculate spiral length of Spiral 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.
