ANGLE OF REFLECTION ON A PLANE MIRROR DRIVER

Centre of curvatureĬentre of spherical lens of which the lens forms a part. The following are the terms related to the lenses:

ANGLE OF REFLECTION ON A PLANE MIRROR DRIVER

The image seen in the mirror is laterally inverted, looks right as left and the left as right.Įxample: The word �AMBULANCE� is written in laterally inverted position on the vehicle so that when the driver of a car, which is moving in front of an ambulance, observes the same in the mirror it looks clearly and gives a way for the AMBULANCE. The image is as far behind the mirror as the object is in front.Ī line joining equivalent points on the object and image passes through the mirror at right-angles. The incident ray (incoming ray), reflected ray (outgoing ray) and the normal can all be drawn on one flat piece of paper. Light is reflected with the same angle as it arrives on to the mirror. Plane of incidence: The plane in which the normal and the incident ray lie, is called the plane of incidence. The incident ray, the reflected ray, and the normal all lie in the same plane. A mirror with a flat or planar reflective surface is called a plane mirror. In diagram, QON is the angle of reflection. The angle of incidence is equal to the angle of reflection.Ģ. When a ray of light strikes a mirror, it is reflected by obeying following laws of reflection.ġ.

The coordinates of A, B, C are given asįind reflected position of triangle i.e., to the x-axis.Definition Of Reflection In Plane Mirrors The last step is the rotation of y=x back to its original position that is counterclockwise at 45°.Įxample: A triangle ABC is given. After it reflection is done concerning x-axis. Reflection about line y=x: The object may be reflected about line y = x with the help of following transformation matrixįirst of all, the object is rotated at 45°. This is also called as half revolution about the origin.Ĥ. In this value of x and y both will be reversed. In the matrix of this transformation is given below Reflection about an axis perpendicular to xy plane and passing through origin: The following figure shows the reflection about the y-axisģ. The object will lie another side of the y-axis. light including predictions of images of plane mirrors, angles of reflection. Here the values of x will be reversed, whereas the value of y will remain the same. Mirror worksheet 1 - ray diagrams Refraction: If one has ever used a pool. Caution: Avoid putting ngerprints on the surfaces of the optical elements. When dealing with refraction, the angle of transmission is dened as the angle between the transmitted ray and the surface normal at that point. A mirror has a smooth surface and reflects light at specific angles. REFLECTION AND REFRACTION 80 surface of the mirror. Reflection about y-axis: The object can be reflected about y-axis with the help of following transformation matrix The angle of reflection equals the angle of incidence. Mark on it the angle of incident and the angle of reflection (CBSE 2014). The images compare the waves reflected from a plane mirror and at a. The object will lie another side of the x-axis.Ģ. List four characteristics of the images formed by plane mirrors. The law of reflection holds true irrespective of the surface the light gets reflected from. Following figures shows the reflection of the object axis.

In this transformation value of x will remain same whereas the value of y will become negative. Reflection about x-axis: The object can be reflected about x-axis with the help of the following matrix

Reflection about an axis perpendicular to xy plane and passing through the originġ.

The mirror image can be either about x-axis or y-axis. It is a transformation which produces a mirror image of an object.
