The image formed by a plane mirror is always virtual and erect. The size of the image is equal to that of the object. It is located as far behind the mirror as the object is in front of it. ...

The two laws of reflection are: (i) The angle of incidence is equal to the angle of reflection. (ii) The incident ray, the normal to the mirror at the point of incidence, and the reflected ray all lie in the ...

The fact that a small source of light casts a sharp shadow of an opaque object indicates that light travels in straight lines. This phenomenon is usually represented as a ray of light, and the study of such properties helps ...

Some common optical phenomena include image formation by mirrors, the twinkling of stars, the beautiful colors of a rainbow, and the bending of light by a medium.
