Question

Which of the following sets of apparatus will be useful to prove the law of reflection?
A. A Spherical Mirror, a Sheet of white paper
B. A plane mirror, a laser light, a pencil, a protractor, a sheet of white paper.
C. A Mirror, a sheet of black paper
D. A laser light.

Answer 1

To Prove the Law of reflection, A ray of laser light is allowed to hit the mirror and the light is reflected.
By using the pencil, mark the path of light and mirror base. The angle of incidence and angle of reflection is measured using the protractor, and the angle of incidence is equal to the angle of reflection.
Now mark the incident ray and reflected ray they normally lie on the plain paper hence both laws are proved.

Complete step-by-step solution:
Generally, the law of reflection states that the angle of reflection is equal to the angle of incident. These angles are measured perpendicular to the surface at the point where the light ray hit.
When we see our face in the mirror, it appears like our image is actually behind the mirror. The mirror has a smooth surface and reflects light at specific angles. Light gets diffused when it is reflected from the rough surface.
These Mirror images can be photographed and videotaped.
The reflected ray is used to be in the plane defined by the incident ray and normal to the surface at the point of contact of the incident ray.
The images produced by the Curved mirrors can be real or virtual. The Images produced by the Plane mirrors are always virtual. They cannot be collected by the screen.
The angle of reflection is the angle Measured from the reflected ray to the normal surface.
Hence, the answer is Option (B) A Plane mirror, a laser light, a pencil, a protractor, a sheet of white paper.

Note: The first law of reflection states that the incident ray and the reflected ray are normal to the surface of the mirror and lie in the same plane. The angle of reflection is equal to the angle of an incident which is the second law of reflection. The incident and reflected angles are Measured Concerning the normal to the mirror. Diffuse reflection helps to see the objects and it is responsible to see the illuminated surfaces from any position.
