plz answer it, it's urgent...
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.
plz write in ur own words so I can understand it easily.
don't copy from Google or any other website...
plz plz plz

Hey There! ☺️
AIM:- To show that the incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.
MATERIALS REQUIRED :- a white coloured piece of paper (A-4 size) , a drawing board,a short flat-headed pin, a groom .
PROCEDURE :-
(a) A white coloured piece of paper on a drawing board is fastened securely in position.
(b) A strip of plane mirror is to be taken and placed in the way made by continual treading of beam of light.
(c) The beam of light ray of the surface would be reflected back without absorbing it.
(d)The angle which an incident line makes with a perpendicular to the surface and the angle made by a reflected ray with a perpendicular to the reflecting surface on the sheet of paper is drawn.
(e) The incident ray of light that strikes a surface and reflected rays that represents the light reflected by the surface along the paper is observed.
(f) Now the given sheet of paper is twisted a small-scale at the location of the reflected that is reflected from a surface.
(g) Possessing the beam of incident ray and the normal in the plane of the drawing board, the reflected ray is attempted to be seen now.
OBSERVATIONS :- the incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.
_______________________________________________
THEORY BEHIND THIS ACTIVITY
When the entire sheet of paper is spread on the table, it represents one position. The incident ray, the usual at the factor of incidence and the reflected ray are all in this plane. After we bend the paper we create a plane one-of-a-kind from the plane wherein the incident ray and the usual lie. Then we don't see the reflected ray. It suggests that the incident ray, the usual at the point of incidence and the reflected ray all lie within the same plane.
