Question

state the rules used for drawing ray diagram for the formation of an image by a convex lense​

Answer 1

Answer:

Step 1

Using rule 1, draw a line from the top of the object, parallel to the principal axis, to the mid-plane of the lens, then draw the refracted ray line from the mid-plane of the lens through the focal point.

Step 2

Using rule 2, draw a line from the top of the object, straight through the optical centre of the lens.

Step 3

The point of intersection between the refracted ray lines is the top of the reflected image.

If the ray lines are diverging, use dashed lines to extend them backwards until they intersect .

If the bottom of the object lies on the principal axis, the bottom of the refracted image will also lie on the principal axis.

If the bottom of the object does not lie on the principal axis, repeat steps 1-3 to locate the bottom of the refracted image.
