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.

Why extended source is used in the newtons ring experiment?

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.


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


What is the order of the colours obtained in newtons ring experiment if illuminated with white light?

The centre spot will be dark even when we use white source. As the radius of the ring is directly proportional to the square root of the wavelength, the violet being the shortest wavelength will come first and red will be the last as its wavelength is the longest in the visible region. Any how we cannot get sharp coloured rings around the black spot. Instead overlapping occurs and just multicoloured rings can be seen.


What do ring stands do?

The ring stand holds an iron ring, or other support apparatus, depending on what the experiment calls for.

Why should you use a convex lens of large radius of curvature in performing newtons ring experiment?

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


Why does your ring fingure stand up by it self?

The ring finger has the least independent movement compared to other fingers, which can make it harder to control individually. The muscles and tendons that control finger movement are connected, so when one finger is extended, the others may follow involuntarily. This can result in the ring finger standing up slightly when the adjacent fingers are extended.

Why do you take plano convex lens with a spherical surface of a large radius of curvayure in the newtons ring experimental set up?

In Newton's ring experiment, a plano-convex lens with a large radius of curvature is used to ensure that the interference fringes produced between the lens and the flat glass plate can be easily observed and analyzed. The large radius of curvature helps in creating distinct and well-defined interference patterns, which are essential for accurate measurement and analysis of the rings.
