Question

1. apply student a sits in a chair facing a mirror and sees the reflection image b of student b in the mirror. show the actual position of student b.

Explanation:

Step1: Recall reflection property

The object and its image in a plane - mirror are equidistant from the mirror and are on a line perpendicular to the mirror.

Step2: Draw the line

Draw a line from point \(A\) perpendicular to the mirror.

Step3: Locate the object

Since \(B'\) is the image of \(B\), measure the distance from \(B'\) to the mirror along the perpendicular line from \(B'\) to the mirror. Mark a point \(B\) on the other side of the mirror at the same distance from the mirror as \(B'\) is from the mirror along this perpendicular line.

Answer:

Locate point \(B\) on the other side of the mirror such that the perpendicular distance from \(B\) to the mirror is equal to the perpendicular distance from \(B'\) to the mirror, and \(B\) and \(B'\) are on the same line perpendicular to the mirror.
