Focal length given radius

WebYou are given a spherical mirror and wish to determine its properties. You place an object on its axis, 33.5 cm in front of it, and discover that the mirror creates a virtual image located 14.5 cm from the mirror. Determine the mirror's focal length / in centimeters. Calculate the mirror's radius of curvature C in centimeters. WebFocal length = the distance from the subject to the lens + the distance from the lens to the camera sensor. You also need to understand if your lens is concave or convex to determine focal length. A convex lens (also known as a converging lens) and a concave lens (also called a diverging lens) focus light at different points.
