Con-caved mirror
A plane mirror is FLAT, whereas mirrors can be also convex (as with the back of a spoon) or concave (as is the case with the inside of a spoon). In other words, mirrors can be CURVED.
Because the spoon is curved inward so your reflection appears to be upside down.+++For an explanation look up the principles of concave mirrors.
The mirror on the back of a spoon is a convex mirror.
A spoon acts as a rough-and-ready convex or concave mirror, depending on which side of ityou admire yourself in, so it follows the rules of curved mirrors. Also, a spoon's geometry is not that of a spherical or parabolic cap so will give a distorted image anyway.
The inside of a spoon is a concave mirror. The outside of a spoon is a convex mirror.In the cartoon, "Rose is Rose", Rose's husband enjoys glimpsing his wife mirrored by a spoon, because she is slender, but he prefers a more zaftig figure.
A mirror that bows inward is called concave. The opposite, a mirror that bows outward would be called convex. Convex mirrors are used to to increase the field of view around corners and blind spots. Concave mirror serve no purpose other than novelty (making you appear thin or odd)
look at it
because the light travels str8 and if it hits a curved reflection your eves will follow there fore it looks upside down Because its a convex mirror. A regular mirror shifts everything from left to right but a convex mirror reverses on a horizontal plane versus a vertical plane.
a spoon is a convex mirror because it shows far objects in small sizes or it shows the far objects in a diminished size ...
You'd actually see your upside-down reflection in the bowl of a spoon (the part where the food goes); any reflection you see on the opposite side will always be upright. The inside of a spoon acts as a concave mirror, which have the interesting property of creating an inverted image when the object being reflected is located outside the focal point. If you hold the spoon as close to your face as you can, you'd see your reflection upright.
The side you put the food on.
mirror, spoon, metal, ect.
