The correct Answer is:
To determine the correct ray diagram for a student viewing an object O by reflection in a plane mirror, we can follow these steps: ### Step 1: Understand the Laws of Reflection The laws of reflection state that: 1. The incident ray, the reflected ray, and the normal (a line perpendicular to the surface at the point of incidence) all lie in the same plane. 2. The angle of incidence (the angle between the incident ray and the normal) is equal to the angle of reflection (the angle between the reflected ray and the normal). ### Step 2: Draw the Plane Mirror Start by drawing a straight vertical line to represent the plane mirror. ### Step 3: Identify the Object O Place the object O (which the student is viewing) in front of the mirror. This object can be represented as an arrow or any shape. ### Step 4: Draw the Incident Ray From the top of the object O, draw a straight line towards the mirror. This line represents the incident ray. Make sure to label the angle between this ray and the normal line as the angle of incidence (i). ### Step 5: Draw the Normal Line At the point where the incident ray meets the mirror, draw a dashed line perpendicular to the mirror. This is the normal line. ### Step 6: Draw the Reflected Ray From the point where the incident ray meets the mirror, draw another straight line that reflects off the mirror. This line represents the reflected ray. Make sure to label the angle between this ray and the normal line as the angle of reflection (r). ### Step 7: Ensure Angles are Equal Check that the angle of incidence (i) is equal to the angle of reflection (r). This verifies that the laws of reflection are being followed. ### Step 8: Indicate the Image Finally, indicate the position of the image of object O in the mirror. The image will appear to be behind the mirror at the same distance as the object is in front of it. ### Summary of the Diagram The final ray diagram should show: - The object O in front of the mirror. - The incident ray approaching the mirror. - The normal line at the point of incidence. - The reflected ray leaving the mirror. - The angles of incidence and reflection marked and equal. ---

If the object is placed 20 cm in front of the mirror, how far is the screen from the object?
