Question

describe an activity to show that the incident ray, the reflected ray and the normal at the point of incidence lie in the same plane

Answer 1

Hope it is helpful.

Answer 2

Answer:

Required components are as follows:

• A small mirror
• Brick for the support of the mirror
• A sheet of paper
• A pencil
• D scale

Step 1: Now put the mirror piece on the sheet of paper with the help of the brick. Make sure the mirror is standing straight so that no errors can be found or seen further.

Step 2: Now draw an incident line and name it AB.

Step 3: Observe the reflected line of the same in the mirror, and mark it on the sheet of paper.

Step 4: Now remove the mirror as well as the brick as its work is done here.

Step 5: Draw a perpendicular on the line that you marked in step 3 with the help of a D. (A perpendicular is drawing of a 90 degrees angle).  

Step 6: Join the points to make the reflected rays.

Result: You can observe that the incident rays, the reflected rays, and the normal at the point of incidence lie on the same plane.
