Question

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

Answer 1

Answer:

hope it may help you

it is an activity

Answer 2

Answer:

Place a plane mirror on the table.

Take a paper sheet and make a small hole in its centre.

Make sure that the light in the room is not bright. Hold the sheet normal to the table.

Take another sheet and place it on the table in contact with the vertical mirror.

Draw a normal line on the second sheet from the mirror.

Now, light a torch and focus the torch on the mirror through the small hole such that the ray of light falls on the normal at the bottom

of the mirror. ( as shown in the diagram)

When the ray from this hole is incident on the mirror, it gets reflected in a certain direction.

You can easily observe the incident ray, reflected ray and the normal to the mirror, at the point of incidence on the sheet placed on the

table.

This shows that the incident ray, the reflected ray, and the normal, at the point of incidence, all lie in the same plane.
