Question

33 Draw ray diagrams for the following positions of convex lens?
A) Object is placed at F.
B) Object is placed at 2F,​

Answer 1

Answer:

sorry. can't answer your questions

Answer 2

Explanation:

Here, Object AB is at 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 refracted rays meet is point A

And the image formed is A'B'

This image is formed at 2F 2

We can say that

• Image is Real

• Image is Inverted

• Image is exactly the same size as

that of Object
