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
convex lens with a diameter of 70mm and focal length of 100mm was used in the spotlight imaging experiment Production name Plano-Convex Lens Material K9,JGS1,CaF2,Si,Ge ,ZnSe. Focal Distance ±5mm~±1000mm±1% Size 1mm-30...
Photo: The adjustable zoom lens on this Canon digital camera zooms three times (3×). Its focal length changes between 5.8–17.4mm, which is a ratio of 1:3.An ordinary lens has a fixed focal length—so it does one job and one job only. But what if you want it to magnify a ...
A spherical mirror and a spherical lens each have a focal length of, -15 cm. The mirror and the lens are likely to be : (a) both concave. (b) both convex. (c) the mirror is concave but the lens is convex. (d) the mirror is convex but the lens is concave. View ...

An object is at a distance of 20 m from a convex lens of focal length 0.3 m. The lens forms an image of the object. If the object moves away from the lens at a speed of 5 m/s, the speed direction of the image will be:
