f=-10cm u=-15cm By using mirror's formula, = 1/f=1/v+1/u = 1/-10=1/v+1/-15 = 1/v=1/-10-(1/-15) = 1/v=-1/30 Therefore, v=-30cm

Object distance u = -15cm Focal length f = - 10cm Find = image distance v Solution Write formula 1\v -1\u =1\f So 1\v = 1\f + 1\u 1\v = 1\(-10) +1\(-15) 1\v = 1\-10 - 1\15 1\v = -3-2\30 1\v = -5\30 1\v = -1\6 1\v = -6 The negative signs shows that an inverted image is generated at a distance of 6cm front of tbe given concave mirror.
