Question

when the object of 6cm height is placed infront of a concave mirror of real image is formed 16 cm away from mirror (1 ) what will be the height of image (2)determin the magnification of image​

Answer 1

Answer:

Given that,

The object distance u=−6cm

Now, magnification is

  m=OI

 m=f−uf

 6I=−f−(−4f)−f

 I=−2cm

Hence, the length of image is -2 cm
