Question

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

Answer 1

Take a white sheet paper and place it on the table.

Let the sheet be a little outside the edge of the table.

Take a comb and close all its opening except the middle.

Hold the comb perpendicular to the sheet of paper.

Now, through light of the torch from through the opening of the comb

You will see the incident and the reflected ray (If you make figure)

Now, we make the normal.

Now, u can cut sheet from the point of reflection.

Hence, incident ray, reflected ray and the normal lie in same plane.

Sorry i didn't able to make figure of the activity because i dont know how to set figure here from gallery but u can make figure according to my answer thank u.
