Which among the following is not true for a plane mirror?a)Image forme...
Explanation:
A plane mirror is a flat, smooth surface that reflects light. When light rays interact with a plane mirror, they undergo reflection. Here are the given statements and their explanations:
a) Image formed is always erect:
When an object is placed in front of a plane mirror, the image formed is always erect, which means it is in the same orientation as the object. This is because the reflected rays do not cross, so the top of the object appears at the top of the image and the bottom of the object appears at the bottom of the image.
b) Image is always formed at infinity:
This statement is not true for a plane mirror. The image formed by a plane mirror is always virtual and appears to be located behind the mirror. However, the image is not formed at infinity. The distance between the object and the image is equal to the distance between the object and the mirror.
c) Lateral inversion always takes place in a plane mirror:
When an object is reflected in a plane mirror, the image appears laterally inverted or horizontally flipped. This means that the left side of the object appears as the right side in the image, and vice versa. Therefore, lateral inversion always takes place in a plane mirror.
d) Image formed by a plane mirror is always virtual:
The image formed by a plane mirror is always virtual, which means it cannot be projected onto a screen. It can only be seen by an observer looking into the mirror. The virtual image appears to be behind the mirror and cannot be formed on a screen.
In conclusion, the statement that is not true for a plane mirror is option 'B' - "Image is always formed at infinity." The image formed by a plane mirror is virtual and appears to be located behind the mirror, but it is not formed at infinity.
