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: Note: The left side of...
A beam of light converges at a point P. Now a lens is placed in the path of the convergent beam 12 cm from P. At what point does the beam converge if the lens is (a) a convex lens of focal length 20 cm, and (b) a concave lens of focal length 16 cm? View Solution Q2 A...
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

calculated. We arive at the conclusion that for the Gaussian beam the cat's eye reflector is ideal and gives best parallelism of the incident and the reflected beam when the focal length of the convex lens, the radius of curvature of the concave mirror and the distance between them are ...

In the human eye, as the image always needs to be formed on the retina, di is fixed to be the distance between the lens and the retina, which is about 0.017 meters (17 mm), and the focal length of the lens need to be ...
The wavelength of the laser is 0.532 µm, the distance between the convex lens and the object is 10 mm. The focal length of the convex lens is 50 mm. d2 and d3 are 20 mm and 40 mm respectively. Fig. 5(b) shows the achieved compressed image with half-length of the original ...
