- f is the focal length of the combination,- f1 is the focal length of the first lens (concave lens),- f2 is the focal length of the second lens (convex lens). Step 1: Identify the focal lengths- The focal length of the concave lens f1=−12 cm (negative because it is a ...
A concave mirror has a focal length of 13 cm. The mirror forms an image located 40 cm in front of the mirror. What is the magnification of the mirror? Magnification: The ratio of the height of the image (h') f...

An illuminated object is placed at a distance 15 cm in front of a convex lens of focal length 12cm. If a plain mirror is placed behind the lens at a distance 45 cm, a distinct image is formed in front of the lens (in the object side) on the screen. Find the distance of the scre...
47. While performing an experiment for determining the focal length of a concave mirror by u-v method, a student recorded the given sets of the positions (in cm) of the object and the corresponding image on the bench as (12.51).(18,54), (30,50),(48, 34),(42,42) and (78. 98...
