A concave mirror of focal length 20 cm is placed 40 cm away from a convex mirror of focal length 15 cm . An object is placed between both the mirrors, 15 cm away from the convex mirror. Find the position of image formed by reflection from concave mirror followed by convex mirror. What is nature of the image formed ?

AI Generated Solution

To solve the problem step by step, we will first analyze the situation with the concave and convex mirrors and then apply the mirror formula to find the position of the image formed by each mirror. ### Step 1: Identify the parameters - Focal length of the concave mirror (F1) = -20 cm (negative because it is concave) - Focal length of the convex mirror (F2) = +15 cm (positive because it is convex) - Distance between the mirrors = 40 cm - Distance of the object from the convex mirror (U1) = -15 cm (negative as per the sign convention) ...
