Question

Draw Ray Diagrams Of Image Formation.There are 8 images in total including concave and convex lenses both.

Explain the diagram also.

Answer 1

Answer:

The "three principal rays" which are used for visualizing the image location and size are: For an object outside the focal point, a real inverted image will be formed. Move the point named " Focus' " to the right side of the lens to change to a concave lens.

Answer 2

In this Case, Object is kept far away from lens (almost at infinite distance)

So, we draw rays parallel to principal axis

Since ray parallel to principal axis passes through the Focus

Both rays meet at focus after refraction

Hence, Image is formed at F 2

And it is very very small

We can say that

Image is Real

Image is Inverted

Image is Smaller than the Object (Highly Diminished)

In this 2nd Case Here, Object AB is beyond 2F 1

First, we draw a ray parallel to principal axis

So, it passes through focus after refraction

We draw another ray which passes through Optical Center

So, the ray will go through without any deviation

Where both rays meet is point A'

And the image formed is A'B'

This image is formed between F 2 and 2F 2

We can say that

Image is Real

Image is Inverted

Image is Smaller than the Object (Diminished)
