Problem 2: A 1.49-cm-high object is placed 6.47 cm in front of a concave mirror. It forms a virtual image that is upright and 5.25 cm high 3) How far is the image from the mirror?

Solution

As

m = hi/ho = -di/do

As hi = 5.25 cm. ho = 1.49 cm, do = 6.47 cm, then

|di| = 22.8 cm [di = -22.8 cm as it is virtual, but the question asks how far, so we take it positive.] [ANSWER]
