Question
An object is situated at a distance of 12 m from a plane mirror. The distance at which its image is formed is ____ m.
Hint:
A plane mirror forms an image same as the object( height, size )
The correct answer is: 12
That is, the rays that appear behind the mirror without actually intersecting are virtual. . The distance from the plane mirror to the object is equal to the distance from the plane mirror to the image.
So, the distance of the object from the mirror = distance of the image from the mirror = 12

An incident ray goes along the reflecting surface. The angle of reflection is ____ degrees.
When the angle along the reflecting surface , the incident ray is perpendicular to the reflecting surface. We know by the first law of reflection that angle of incidence is equal to angle of reflection . Here, the angle of incidence is 90 degrees so the angle of reflection will also be 90 degrees.
