Question

Where is the image located when an object is placed 60.0 cm from a mirror which has a focal length of 20.0 cm ?

Answer 1

Answer:

30.0 cm

Explanation:

Using the mirror formula-

1/v + 1/u = 1/f

where u = +60.0 cm and f = +20.0 cm.

Putting the values in the formula

1/(60.0 cm) + 1/v = 1/(20.0 cm)

1/v = 1/(20.0 cm) - 1/(60.0 cm) = 2/(60.0 cm)

v = 30.0 cm

Thus, the image is located 30 cm from the mirror.
