Question

A converging mirror is a:
A. Plane mirror
B. Concave mirror
C. Convex mirror
D. Rear view mirror

Answer 1

Hint:Converging and diverging action for a beam of light is done by spherical mirror. The mirror is known as a converging mirror when it converges a parallel beam of light falling on it at a focal point. On the hand the mirror which diverges from the parallel beam of light falling on it is called a diverging mirror. The same convention goes for the lenses. In case of mirror reflection of light takes place while in case of lens refraction of light takes place.

Complete answer:
A converging mirror is a mirror in which the rays traveling parallel to the principal axis after reflection seem to meet at a point or actually meet at a point. This point of intersection is known as the focus. This converging action for the rays of light can be done by a concave mirror which is a type of spherical mirror whose inner surface is reflecting and the outer surface is silvered. Convex mirror is also a type of spherical mirror whose inner surface is silvered while the outer surface acts as a reflecting surface. It diverges a beam of light traveling parallel to the principal axis after reflecting through it.

Thus a converging mirror is a concave mirror.

Note:Concave mirror acts as a converging mirror by focusing a parallel beam of light at a point known as the focus. Concave mirror is a part of a spherical mirror whose inner surface is reflecting while the outer surface is silvered to enable reflection. It converges a beam of light travelling parallel to the principal Axis at a point known as a focus and therefore is known as a converging mirror. The distance of the focus from the pole of the mirror is known as the focal length. It is generally used in reflecting telescopes.
