An object is 36 cm in front of a concave spherical mirror, and the image is 9.0 cm in front of the mirror. What is the radius of curvature of the mirror? Give your answer in cm.
Added by Sollo P.
Step 1
The focal length (f) is the distance from the mirror to the focal point. In a concave mirror, the focal length is positive. We can use the mirror equation to find the focal length: 1/f = 1/v - 1/u Where: f = focal length v = image distance (distance of the image Show more…
