## What is the radius of plano convex lens?

In a plano convex lens the radius of curvature of the convex lens is **10cm**. If the plane side is polished, then the focal length will be. (Refractive index =1.

## What is the radius of curvature of the flat side of a plano convex lens?

In a Plano-convex lens, the radius of curvature is **10cm**.

## What is the formula of plano convex lens?

**f=R/2**.

## How does a plano convex lens work?

More specifically, the two surfaces of a plano-convex lense function **together by focusing parallel light rays to a positive focal point**. … The curved surface of a plano-convex lens has a focusing effect on light-rays, while the plane surface does not have a focusing or de-focusing effect.

## What are plano convex lens?

Plano-convex lenses are **positive focal length elements that have one spherical surface and one flat surface**. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.

## What is the unit of radius of curvature?

Let’s measure length in meters (m) and time in seconds (sec). Then the units for curvature and torsion are both m−1. Explanation #1 (quick-and-dirty, and at least makes sense for curvature): As you probably know, the curvature of a circle of radius r is **1/r**.

## What is the minimum distance between an object and its virtual image in case of a concave lens?

Answer: The minimum distance between an object and its real image in the case of a concave mirror is **Zero**.

## What if the radius of curvature of plano convex is increased?

In figure 3, you can see the drawing represents a plano-convex lens with a radius of curvature of 25.4mm. … (Figure 5). Just as with convex lenses, assuming the diameter of the lens remains constant, as the radius of curvature increases, the curvature of **the lens become more and more shallow**.

## What is the focal length of plano concave lens?

The focal length of a plano convex lens is **′f′** and its refractive index is 1.5. It is kept over a plane glass plate with its curved surface touching the glass plate. The gap between the lens and the glass plate is filled by a liquid. As a result, the effective focal length of the combination becomes 2f.

## Why R is at infinity in plano convex lens?

the plano convex lens is plane from one side . and in the mirror formula R1 and R2 are the radii of the two circular parts. **since one part is flat it is considered to have an infinite radius**.
