Lin yao looks at the back of a spoon. how should she describe her reflection? a. upside down and smaller b. upside down and larger c. right-side up and smaller d. right-side up and larger

The correct answer is C, right-side up and smaller.

It is the most common example of spherical mirrors. The inside of the spoon acts like a concave mirror and the back side of it like a convex mirror.

A convex mirror always forms a real and diminished image. That is, the image formed is erect or right-side up and smaller in size. Therefore, Lin Yao should describe her reflection on the back side of the mirror to be right-side up and smaller.

Explanation :

There are three types of mirrors i.e. plane mirror, concave mirror, and the convex mirror.

The concave and convex mirrors are spherical mirrors. The back side of a spoon forms a convex mirror.

The image formed by a convex mirror is the real and diminished image.

Also, the image is erect. While on the front side of the mirror, the concave mirror is formed.

So, the correct option is (C) "  right-side up and smaller ".
