D
Correct answer
Explanation
Statement (1) is wrong.To view an image of yourself in a plane mirror, you will need an amount of mirror equal to one-half of your height.
Statement (2) is wrong. A convex mirror has an outward curve, meaning that the reflecting surface is focused towards the source of light falling onto it. Such mirrors create a virtual image of the object and this image is lightly diminished as compared to the object's actual size. This is why in some of the cars, the passenger side-mirror is generally inscribed with a warning, which states that “Objects in the mirror are closer than they appear”. The convex mirror produces an upright image of any object and offers a wide viewing area as compared to the plane mirror. The usage of this type of mirror can be perceived on the rear-view mirror and side-view mirror of the cars, and the motorcycles. These mirrors in the vehicles help in cutting down the blind spots as long as the object is in their focus.
