Name the two types of spherical mirrors. What type of mirror is represented by the:(a) back side of a shining steel spoon?(b) front side of a shining steel spoon?
The two types of spherical mirrors are:
1. Concave mirror
2. Convex mirror
The types of mirrors represented by the:
(a) back side of a shining steel spoon $-$ convex mirror.
(b) front side of a shining steel spoon $-$ concave mirror.
Explanation
A convex mirror, also known as a diverging mirror, as it is curved outward in the middle and when light strikes the reflective surface of the mirror, it diverges light rays.
When parallel incident light rays fall on the surface of the mirror, they get reflected and appear to diverge from the principal focus (F).
It always forms virtual, erect, and diminished images irrespective of the distance between the object and the mirror.
A concave mirror, also known as a converging mirror, as it is curved inward in the middle and when light strikes the reflective surface of the mirror, it converges light rays.
When parallel incident light rays fall on the surface of the mirror, they get reflected and meet at a particular point and form the image.
Depending on the position of the object with respect to the mirror, the types of images it forms are real, inverted as well as virtual and erect image, also the size of the images formed are magnified, diminished as well as the same size as that of the object.
