A point object O is placed on the principal axis of a convex lens of focal length 10 cm at 12 cm from the lens. When object is displaced 1 mm along the principal axis away from lens, magnitude of displacement of image is x1 .When the lens is displaced by 1 mm p...
A concave mirror of focal length f1 is placed at a distance of d from a convex lens of focal length f2. A beam of light coming from infinity and falling on this convex lens concave mirror combination returns to infinity. The distance d must equal View Solution Q2 An object...

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...
<p>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.</p><p>1. <strong>Understanding the Lens Maker's Formula</strong>: The lens make
