Convex Lens is a structure of two spherical surfaces joined together such that they act as converging lens, i.e. converge the rays passing through it. Focal length of convex lens is positive. Answer and Explanation:1 Note: The left side of...
In an experiment to measure the focal length of a convex lens, the measured focal length is shorter than the actual value. What could be the cause? A. The object distance is measured inaccurately and is too large. B. The image distance is measured inaccurately and is too small. C. The...
An object is placed 13.3 cm away from a convex mirror with a focal length of magnitude 7.00 cm. (a) Is the sign of the focal length negative or positive? (b) Find the image distance q. A concave, spherical mirror and a thin, converging lens are both measured in air (n ...
Biconvex lens are also known as double convex lens. A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conju...
Focal length of convex lens will miximum for (a) blue light (b) yellow light (c) green light (d) red light
In the experiment of finding the focal length of a convex lens, we should use: A. A ruler and a white paper B. A protractor and a mirror C. A ruler and a concave lens D. A protractor and a white paper 相关知识点: 试题来源: ...
To solve the problem, we will use the lens maker's formula, which relates the focal length of a lens to its refractive index and the radii of curvature of its surfaces.1. Understanding the Lens Maker's Formula: The lens make
, find the position, nature and height of the image. Solution Step 1 - Given data The height of the object h=7 cm The distance of the object from the optical center of the lens u=-12 cm The focal length of the lens f=+8 cm (The focal length of a convex lens is positive) ...
The pressure tube is made up of one or more chambers, with only the central one pressurised. A metal or plastics material ring encircles the pressure tube and lens and hold them under tension. The focal length of the lens is adjusted by opening one or more of the valves, thus altering ...
