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

2)The rings observed have a large diameter and hence error in the measurement of their diameter is minimised.

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.
What kind of lens does a projector use?
projector have concave or convex
Is a fish-eye lens convex?
Yes. Because convex lens produce real image.. so Fish eye has convex lens
A magnifying glass is also called what?
The answer is both convex and converging
What is the use of the newton's rings?

What is curvature of a convex lens?
The curvature of a convex lens refers to the amount of curvature or bend present on each of its surfaces. It is typically defined by the radius of curvature, which indicates how sharply the lens surface is curved. This curvature plays a significant role in determining the focal length and optical properties of the lens.
The curvature of an eye's convex lens is change by?
Muceles
What are the five components fused called?
Sacral Curvature (convex)
Has a convex lateral surface called greater curvature and a concave medial surface called lesser curvature?
The stomach has a greater and lesser curvature. The greater curvature is the more lateral of the two.
How do you derive relation between focal length and radius of curvature of convex mirror?
For a convex mirror, the focal length (f) is half the radius of curvature (R) of the mirror. This relationship arises from the mirror formula for convex mirrors: 1/f = 1/R + 1/v, where v is the image distance. When the object is at infinity, the image is formed at the focal point, and the image distance is equal to the focal length. Hence, 1/f = -1/R when solving for the focal length in terms of the radius of curvature for a convex mirror.
The relation between focal length and radius of curvature of spherical mirror is?
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
What is curvature of a lens?
The curvature of a lens refers to the amount of bending in the lens surface. A lens can have a convex curvature (outward bending) or a concave curvature (inward bending), which affects how it refracts light. Curvature is measured by the radius of curvature, which can determine the focal length and strength of the lens.
Formula of radius of curvature of double convex lens?
The formula for the radius of curvature (R) of a double convex lens is given by R = 2f, where f is the focal length of the lens. The radius of curvature is the distance from the center of the lens to the center of curvature of one of its curved surfaces.
What are the parts of convex mirror?
A convex mirror consists of a reflective surface that curves outward, away from the observer. It also has a focal point located behind the mirror and a center of curvature, which is the midpoint of the mirror's curvature.
Why plano convex lens is used in newton rings experiment?
A plano-convex lens is used in Newton's rings experiment because the convex surface of the lens helps to create a well-defined thin air gap when placed against a flat glass plate. This air gap is where the interference pattern, known as Newton's rings, forms when illuminated with monochromatic light. The curvature of the convex surface of the lens also helps to distribute the pressure evenly, ensuring a better contact between the lens and the glass plate.
What is difference between curvature and radius of curvature?
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
