Question

An object is located 70 cm from a concave mirror with a focal length of 15 cm. What is the image

Answer 1

(a) The distance of the image formed by the concave mirror is 19.1 cm.

(b) The image formed is diminished and real.

Image distance

The distance of the image formed by the concave mirror is calculated as follows;

1/f = 1/v + 1/u

1/v = 1/f - 1/u

1/v = 1/15 - 1/70

1/v = 0.05238

v = 1/0.05238

v = 19.1 cm

The image distance is smaller than object distance, thus the image formed is diminished and real.
