To solve the problem, we will follow these steps: ### Step 1: Identify the given values - Radius of curvature (R) = 20 cm (for a concave mirror, we take this as negative, so R = -20 cm) - Object distance (u) = 15 cm (again, for a concave mirror, we take this as negative, so u = -15 cm) ### Step 2: Calculate the focal length (f) The focal length (f) of a concave mirror is related to the radius of curvature (R) by the formula: ...
