Question

In the image formed by a plane mirror, the left of the object appears on the right and the right appears on the left, this is known as

Answer 1

Reflection

1. Reflection is the phenomenon in which a ray of light traveling in a straight path, after hitting a reflecting surface, returns back in a different path.
2. The ray hitting the reflecting surface is called the incident ray.
3. The ray traveling back from the surface is called the reflected ray.
4. The normal is an imaginary line with respect to which the angle of incidence and angle of reflection is measured.
5. The first law of reflection states that the incident ray, reflected ray, and the normal lie on the same plane.
6. The second law of reflection states that the angle of incidence is equal to the angle of reflection.

Reflection by a Plane Mirror

1. When the light coming from an object reflects from a plane mirror, it forms an image of the object.
2. This image is a virtual image that is formed behind the mirror.
3. This image is obtained by tracing the path of the reflected rays backward.
4. This image is erect and lateral.
5. Hence, in the image formed by a plane mirror, the left of the object appears on the right and the right appears on the left, this is known as a lateral inversion.
