the reflection of a 10.0 cm object appears to be 18 cm tall and 9 cm behind the mirror. what distance is the object from the mirror? cm
Answer
Explanation:
Step1: Recall mirror - image property
In a plane - mirror, the object distance ($u$) is equal to the image distance ($v$).
Step2: Identify the image distance
The image is 9 cm behind the mirror, so $v = 9$ cm.
Step3: Determine the object distance
Since $u = v$ for a plane - mirror, $u=9$ cm.
Answer:
9
