(a) Reflection of light by plane mirror 1. Place a sheet of paper on the cork board, and draw a straight line near the top of the paper. This is the "mirror line". Set up the plane mirror in its holder on the mirror line so that the actual mirror surface is on the line. Adjust the mirror carefully so that the mirror is parallel to line. Size: KB. • • Illustrate graphically the reflection of light from plane, convex, and concave concave mirrors. Geometrical Optics In the study of how light behaves, it is Ray 1: A ray parallel to mirror axis passes through the focal point of a concave mirror or appears to come from the focal point of a convex mirror. Write laws of reflection in a place mirror. The incident ray, the reflected ray and the normal at the point of incidence will be in the same plane. Angle of incidence is equal to angle of reflection. 2. What is light? Learn more about the Laws of Reflection of Light in detail. Characteristics of Images formed by Plane Mirror. a. Images formed by a plane mirror are “Always Virtual”. b. Images formed by a plane mirror are “Erect/Upright”. c. Images formed by a plane mirror are of “same shape and size” as that of an object. Solved Example for You. Q.

  We know that plane mirror reflects reflected ray from one mirror can act as the incident ray on another , the ray of light can be reflected , a reflected light can be reflected like in this image,Example 1 - PeriscopeA periscope is a long, tubular device t. Reflection of light is the phenomenon due to which a light ray traveling from one optical medium to another bounces off its surface with a change of angle.. Regular reflection takes place when a parallel beam of light strikes a smooth polished surface and it is reflected back as a parallel beam of light. Reflections from mirrors and metallic surfaces are examples of regular reflection. Reflection of light - The rebound of rays of light from an elegant and glossy surface is called reflection or reflection of light. It is related to a football bouncing back after colliding with a wall or any hard surface. Laws of Reflection of Light: The angle of reflection and incidence are equal. The incident ray reflected ray and normal to the point of reflection lies in the same plane.   Not clear if you’re looking past the obvious part: reflection turns the incident ray back from the interface, while refraction continues the ray through the interface (though probably with some reflection as well). Beyond that - the reflected ray.

Two plane mirrors A and B are aligned parallel to each other, as shown in the figure A light ray is incident at an angle 3 0 ∘ at a point just inside one end of A The plane of incidence coincides with the plane of the figure The maximum number of times the ray undergoes reflections (including the first one) before it emerges out is _____. Light – Reflection and Refraction Let us recall these laws – (i) The angle of incidence is equal to the angle of reflection, and (ii) The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane. These laws of reflection . The principal focus of a spherical concave mirror is defined as a point on its principal axis where a beam of light parallel to the principal axis converges after being reflected by the mirror. The concave mirror is a spherical mirror whose reflection surface is a section of an inner surface of a hollow sphere. A ray of light parallel to the mirror 's principal axis passes through its focus after mirror reflection as shown in the figure below [Image will be Uploaded Soon] From the above figure, it can be clearly seen that the light rays in concave mirrors travel through the main focus and tend to differ from the main focus in concave mirrors.
