lens formation

Types of Spherical Lenses
1. Converging Lens (Convex Lens): A lens that curves outward, converging light rays to a point. It can form real or virtual images.
2. Diverging Lens (Concave Lens): A lens that curves inward, diverging light rays. It can only form virtual images.
Image Formation in Spherical Lenses
The process of image formation in spherical lenses involves the refraction of light rays. Here's a step-by-step explanation:
1. Object Placement: An object is placed in front of the lens.
2. Light Refraction: Light rays from the object pass through the lens and are refracted (bent).
3. Image Formation: The refracted light rays converge or diverge to form an image.
Converging Lens Image Formation
1. Real Image: When the object is placed beyond the focal length (F), a real, inverted, and magnified image is formed.
2. Virtual Image: When the object is placed between the focal length (F) and the lens, a virtual, upright, and magnified image is formed.
Diverging Lens Image Formation
1. Virtual Image: A virtual, upright, and diminished image is always formed, regardless of the object's distance from the lens.
