Well, a spoon is designed to hold liquids and if it is has the mouth of the spoon bowl pointing up so that it CAN hold liquid is is the right side up (in terms of its use). Consequently if that is the right side up then if you turn it over it will be, by definition, up side down.
Yes. If you hold a spoon with the handle pointing straight down it's left side will look the same as it's right side. Therefore it is symmetrical.
It is right side up.
When you look into the deep side a spoon, you appear to be upside down because the light particles that reach the spoon reflect in different angles, reversing the image inside. This happens because the spoon is not completely flat, and the curves create such an effect.
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).
Yes, when you look at something upside down, the image will be projected upside down onto your retina, located at the back of your eyeball. However, your brain is able to interpret the image and flip it right side up so that you perceive the object correctly.
you go to the bathroom and flip the switch on the right
Yes
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.
you press CTRL + ALT and the up, down, right, or left arrows.
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!
Look under the boot lid and you will find a plastic blanking plate just to the right of centre. Flip this plate out and insert key in the lock that is now exposed. Simple eh!
