- back side of a shining steel spoon?
- front side of a shining steel spoon?
Advertisements
उत्तर
There are 2 types of spherical mirrors; convex mirror and concave mirror.
- The back side of the spoon is a convex surface because it has a curved outward-reflecting surface. As a result, it's known as a Convex Mirror.
- The spoon’s front side has an inward-reflecting curve, making it a concave surface.
