Question

an object 3 cm high is placed at a distance of 16 cm from a concave mirror which produces a real image of 4.5 cm high find the position of the image​

Answer 1

Answer

+ 9 cm

Step-by-step explanation:

H= 3 cm   H'= 9/2cm

u= -6 cm

now M= h'/h= -v/u

therefore 9/2/3= -v/-6

          => 9/2*1/3= v/6

          => 3*6/2= v

          => 9cm= v
