Answered by shivi14151

1/v+1/u=1/f where u =-40cm and focal length of the concave mirror is also negative then image distance 40 cm means object and image are in same distance inverted image same in size magnification is -1 real image

bharu1971p7s82v: Hello lens formula is 1/f=1/v-1/u for mirror only 1/f=1/v+1/u will come

bharu1971p7s82v: In the question it is given as concave lens

bharu1971p7s82v: Dont confuse please
