- Case 1 - Object Is Placed at Infinity
- Case 2 - Object Is Beyond 2F
- Case 3 - Object Is at 2F
- Case 4 - Object Is Between F and 2F
- Case 5 - Object Is at F
- Case 6 - Object Is Between O and F
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 1. Image is Real 2. Image is Inverted 3. Image is Sma...
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 ...
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 1.

Here, Object AB is kept between F 1 and 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 between beyon...
Here, Object AB is kept at F 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 We observe that both rays are parallel to each other Hence we can say that they meet at infinity. Hence, the rays form a...
Here, Object AB is kept between O and F 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 We observe that both refracted rays are diverging It means that they would have met at some point Hence, we e...
Learn how to locate and size the image formed by a single lens using three principal rays. See examples for convex and concave lenses, and for objects inside and outside the focal length.
In this diagram, five incident rays are drawn along with their corresponding refracted rays. Each ray intersects at the image location and then travels to the eye of an observer. Every observer would observe the same image location and every light ray would follow the Snell's Law of refraction.
Learn about convex lenses, their properties, types, and applications with examples and diagrams. Find out how to calculate the focal length and the nature of the image formed by a convex lens.
