Convex and Concave Lenses

Convex and Concave Lenses are Spherical Lenses. We look at the Image Formation by these spherical lenses using ray diagrams. Light ray rules for Convex Lens and Concave Lens are discussed. Using these rules we can find the position and properties of the image. I'll be the object in this video and you need to find my image!

[@NepaliDeepmind]

Here's what I comment: Q¹. Name the lens that always forms a virtual, upright and diminished image. Ans: It is concave lens that always forms a virtual, upright and diminished image. Q². Which lens is used in a magnifying glass and where should the object be placed? Ans: It is convex lens which is used in a magnifying glass & the object should be placed in between the focus and the optical center of the convex lens. Q³. An object of height 5 cm is kept in front of a lens. An inverted image of height 5 cm is formed. Identify the lens & position of the object & image. Ans: It is convex lens. The position of the object & image is 2F (2 times the focus, F). Sir, your video is really highly informative and practical. Thank you so much, Sir. Commented with ❤️ from Dharmendra from Nepal.
