Best ResponseYou've already chosen the best response.0For concave mirror, foacl length is negative. Object distance always negative. The mirror formula is: (1/u) + (1/v) = (1/f) where, u = object distance, v = image distance, and f = focal length Better to convert all units in terms of "metres".

Best ResponseYou've already chosen the best response.0(1/s)+(1/s') = (1/f) (1/s') = (1/f)(1/s) (1/s') = (1/250)(1/375) (1/s') = (1/150) or  0.00667 mm when the object moved 25 mm object > 375 mm  25 mm = 350 mm (1/s)+(1/s') = (1/f) (1/s') = (1/f)(1/s) (1/s') = (1/250)(1/350) (1/s') =  0.00686 mm \[\Delta s' = 0.00667 mm  (0.00686 mm) \]So the image object moved > 0.00019 mm
