You can use the curved part of a spoon as a mirror because it
light.

Explanation:

Geometrical optics is the part of the physics that describes the propagation of light as rays. It studies when the light goes through a material, or reflect on the surface of materials, the words refraction and reflexction described these events.

Basically, according to optics, all what we see is due to the light, to its reflection on different objects. Everything we observe is because the lights reflects on it, and it reaches our eyes. If the light can't reflect on a object, we actually are not able to see that object.

So, in this case, the word that completes the given statement is reflects, because the reflection of the light is what makes possible to use a spoon as a mirror. Additionally, the curved surface of it, reflects an normal and inverse image, depending on the side of the spoon, this phenomena happens because the light reflects in different anlges depending if the surface is concave or convex.

Therefore, the right answer is reflects.

the plateau is likely to turn into a desert do to corrosion.
