Expert Answer

h = 4 cm; u = - 15 cm; 

P = 1 / f = - 10 D 

f = - 10 cm

1 / v = 1 / f + 1 / u = - (1 / 10) - (1 / 15) = (- 3 - 2) / 30 = - 1 / 6

v = - 6 cm

m = h' / h = v / u

h' = - 6 x 4 / (- 15) = 1.6 cm

It is desired to obtain an erect image of an object, using concave mirror of focal length of 15 cm. Where should we place the object? Where will the image of this object be, if it is placed at 30 cm in front of the mirror? Draw a ray diagram for this situation also to justify your answer.
