A concave spoon will appear to turn upside down when immersed in a liquid due to the refraction of light. When light passes from air into a denser medium (like water), it bends and changes direction. This bending of light causes the concave spoon to appear inverted when seen through the water.
your reflection is upside down on the front part of a spoon for one main reason. The interior part of a spoon in 'concave' meaning it curves inward. when light is reflected of a concave surface, it overlaps and is projected off the spoon upside down. ...
The reflection appears upside down in a spoon because of the angle at which the light bounces off the curved surface of the spoon. This causes the light rays to cross when they hit the spoon, creating the flipped image.
The spoon acts as a concave mirror at it's "loading surface". The idol of an object through a concave mirror which is further than the doubled focal length of it, is real, smaller and inverted (upside-down).
What a nice question. These two different images illustrate the difference between a reflection from a concave and a convex surface. However, if you look in a concave beauty/shaving mirror, you'll still find the image erect. For you will be closer to the mirror than the length of its focus. Enlarged a little indeed.
A convex shape curves outward like a bowl, while a concave shape curves inward like a cave. Convex shapes do not make things upside down.
because the spoon is concave, making the reflection upside down

He held his spoon upside down so that its concave side for holding his soup was rendered useless.
An image that is upside down as compared to the object are known as inverted images. Example, the first thing you will notice is that the concave side of the spoon makes your image come upside down. Such an image is called an inverted image.

Concave mirrors are bent in a way that makes you look upside-down. Convex mirrors, on the other hand, are bent in the opposite direction to make you look bigger. If you have a clean and dry spoon, you can look at your face on either side of the spoon, and you'll see your face either upside-down or enlargened. The bending of concave mirrors cause light to bounce in opposite directions when light hit the mirror, so every particle of you and your surroundings would be the opposite of what it really is.
Yes, we do in fact see things upside down until our brain turns it back around for us. You can prove this fact when you look at your self on the outside of a spoon, you will see yourself upside down! In fact our eyes see things the right way up but the image appears upside down in the retina, our brain works so fast that it can interpret the image quickly. +++ The spoon is no test of how sight works, but demonstrates a property of convex mirrors!

When light rays reflect off a concave surface like a spoon, they converge to a point before diverging again. This causes the image to be inverted. The curved shape of the spoon causes the rays to cross at a point, which flips the image upside down due to the reversal of the light rays.
