Solution:Concept: The only kind of mirror that isn't spherical is a plane mirror. It is a straight mirror that creates an image by extending reflected light that strikes the mirror, passing it through the mirror on the other side, and combining the extended lines to create the image.
Convex, concave, and flat mirrors are the three different types of mirrors. These three mirrors each have a smooth surface that is silvered. Straight mirror with a silvered surface on the back is called a plane mirror. Two rays from the object are travelling in the direction of a planar mirror.
One ray strikes the mirror while being perpendicular to the main axis, and it reflects back. A other ray travels in the direction of the pole and is reflected by it. On the opposite side, when these two rays converge, they are both extended backward. The image is formed at the point where these two beams collide.
The image that forms has the following qualities: -The image is virtual and upright.
The image and the object are exactly the same size.
Although the image is created on the other side of the mirror from the pole, its distance from the pole is equal to that of the object.
Hence, the correct option is 4.
