Chapter 18, Problem 60A

To determine

To describe: Physical properties of image formed by convex lens when objected is placed beyond the center of curvature.

Explanation of Solution

Introduction:

Convex lens: It is a type of lens which is relatively thicker in the middle and thin at the upper and lower edges. It has two focus and two radius of curvature. It converges the light rays that is parallel to the principle axis.The converged rays pass through the other focus of the lens.

A convex lens is used in microscope, telescope, camera, magnifying lenses, etc. A convex lens is shown below,

  

Here, F is the focus of the lens.

When the object is placed beyond the center of curvature the image formed is shown below,

  

The image is formed between right hand side F and 2F of the convex lens in above figure.

Here, the physical properties of the image is

• Real image since the light rays actually meets.
• The image formed is inverted meaning upside down.
• The image is diminished since the size of image is small as compared to the object.
