the focal length of a convex mirror น/hose raditFind12 emof carvature ismirror produces three times masnuiñiod

Answer»

Radius is = 2f or f is = R/2 so given radius is 32 cm and focal length will be 32/2 = 12cm hence lens is convex lens it's focal length is +ve

Radius of curvature R = 32 cmR =2ff=R/2f=32/2f=16 cm
