Question

Draw the ray diagram for the image formation in a convex lens when object is kept between 2F1 and F1.

Answer 1

Ray diagram for Convex lens:

When object is placed between 2F (centre of curvature) and F (focus), image characteristics are as follows:

• Image is real.
• Image is inverted.
• Image is magnified.
• Image is formed beyond the centre of curvature.

Refer to attached diagram.

2 rays have been considered in the above diagram (infinite rays are possible):

• One is the paraxial ray from object that passes through focus after refraction.

• Second is the ray passing through optical centre without any deviation.
