Spoon Image Upside Down
The lens of your eye inverts images as well. This is sort of hard to explain so it may be easier to look at the picture.
Your two mirrors only reverse the image from side to side.
Spoon image upside down. Adshelpatcfaharvardedu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A. Wed like to know why youre staring at yourself in a spoon in the first place. I leaned to the left.
Whichever way I moved it kept staring at me. If you could see through the convex side which you cant you would see the image flipped over. If you turn it around the image turns upside down.
That happens once it is very close to the concave side of the spoon. The bowl shape of the spoon reverses it from side to side and from top to bottom. Straight from the Hip.
Here is N David Mermins explanation from his essay Writing Physics. The result is an upside-down. You can understand how a curved mirror behaves by thinking of it.
No matter how you turn the spoon you will still be upside down. The other side is convex which has a focal point on the inside you cant see it. Face reflected in it was upside down.
The concave spoon is a mirror and bounces the light in. The image shifted to the right. But since its curved the rays of light are reflected in different directions depending on where they hit the spoon.
Basically the light waves hit the different parts of the spoon at different angles so theyre all bent a little bit differently. If you go close enough to the spoon before the focal point the image will actually be the right way up. When you look at a spoon however things are a little different.
But we can at least answer the question of why you look upside-down when you. But as you move further away the image will suddenly become upside-down. In other words if the spoon were flat the image would appear normal and as it the spoon starts dipping inward the image starts to get distorted and at some point it flips upside downso once againwhy how when does that happen.
Because it is concave the light is reflected diagonally. In passing through this point rays from the upper part of your face are reflected downward while those from the lower part are reflected upward. When you look at a spoon why is your reflection upside down.
I reached out as unobtrusively as possible and flipped the spoon over. When the image strikes your retina it is upside down and your brain goes through the trouble of turning it right side up. You are upside down just as you are in the spoon.
Youll see yourself with the right side up and the right side down. The shapes of the concave and convex spoon surfaces. The top of the spoon reflects downwards and the bottom reflects upwards.
Why are images upside down when you look into a spoon but not when you turn it over. By the time they come back to you theyve all bent differently in such a way that they end up making you look upside down. That as as well as blurred images of both upside down and right side up images of the finger in fact three images of flipped or inverted as well as the normal version.
But I had polished the back too and there was another image -- only now my forehead was. Because one side of the spoon is concave which flips the image upside down at the focal point. The left side of the spoon will reflect right and vice versa.
If the surface of the object is slanted relative to the light it will cause the light to be reflected at an angle. Well when you look at a spoon and see that your reflection is upside down its because the light rays are hitting the top of the front side of the spoon then bouncing off and hitting the bottom of the spoon which turns the image upside down. Many people should have realised when looking into a concave curved mirror or even a rather reflective spoon in that fact at a close distance you will see a slightly distorted reflection.
A shiny spoon is like a mirror - only curved. I understand the concepts of concave convexwhat I dont understand is WHY HOW and WHEN the image flips. Been Answer Light rays travel in a straight line until they hit something.
The sides of the spoon work just like the two mirrors to reverse the image. Unlike a flat mirror the curved surface of the spoons bowl bounces incoming rays back towards a central focus point lying between your face and the centre of the spoons. Lenses and mirrors work in opposite ways though.
A light ray comes straight back only when it hits an object dead on. Looks like you are getting ready to go for a partyWhy dont you stand here and then. The top of the spoon will reflect downwards and the bottom of the spoon will reflect upwards.
To make it easier to picture think of an enormous spoon about as big as your head not counting the handle. But what does that mean. The front side of the spoon is concave and the back side of the spoon is convex.
A spoon is concave it goes inwards and thats why you see yourself upside down. Mirrors bounce light and lenses bend them. Concave MirrorWhy is your reflection upside down on a spoonWow.
Where it crosses over is called the focal point and when it crosses you see it upside down. Since the surface is completely smooth it gives a mirror image - a specular reflection.
