βοΈ Class: 10th
βοΈ Subject: Physics
βοΈ Chapter: Light: Reflection And Refraction (Chapter 10)
βοΈ Topic Name: Formation of Images by A Convex Lens - Light: Reflection And Refraction | Class 10 Physics Chapter 10
βοΈ Topics Covered In This Video (by Vibhuti Ma'am): This video covers the topic of formation of images by a convex lens as part of the light: reflection and refraction chapter of Class 10 Science, presented by teacher Vibhuti Mam. We'll learn how convex lenses form images, the difference between the size and the position of the object, and how the focal length affects the nature of the image. We'll also explore examples for better understanding of the concepts. This video will give a thorough summary of the key topics in a step-by-step format, making it a great learning resource for Class 10 students.

Points covered in this video:-
Formation of Images by a Convex Lens -
1. Ray incident on the lens in a direction parallel to the principal axis of convex lens.
- On refraction, this ray passes through (second) principal focus of the lens located on the other side of the lens.
2. Ray passing through optical centre C of convex lens passes straight (undeviated) after refraction through the lens.
3. Ray passing through (first) principal focus F1 of convex lens, incident on the lens, becomes parallel to the principal axis of the lens, after refraction through the lens.
- The image is formed at a point where any two of the refracted rays actually meet (for real image) or appear to meet (for virtual image).
- The position, size and nature of the image depend upon the position of the object in front of the lens.
Case 1. When the object is at infinity
We conclude that when the object is at infinity, the image is:
- At second principal focus of the lens
- Real and inverted
- Highly diminished i.e. image is much smaller in size than the object.
Case 2. When the object is held beyond 2F1.
- Formed between F2 and 2F2 on the other side of the lens
- Real and inverted
- Smaller in size than the object.
