Why is my reflection in the spoon upside down?

Question

Is it backwards, too? I forgot to check.

Answer 1

Concave mirror. Real images get flipped. I can't draw the ray-trace-diagram for you. Here's the wiki link if you want.

Notice from that first diagram that if you bring your face inside the focal length (half the radius of curvature), the image becomes virtual and right-side-up. When you bring your face back (second diagram), then the image is real (light rays converge and cross in front of the spoon) and inverted.

The question of backwards depends on what you mean by backwards.

In a regular mirror, x and y (left/right and up/down) are untouched and z(foreward/back) is flipped. This gives you an image with negative parity so right hands become left hands. In your spoon mirror, x is untouched but y and z are both flipped. So the image has positive parity. Your right cheek is the image's right cheek. The image is just a 180 degree rotation of your face--as if you did a somersault and were looking back at yourself.

Answer 2

Because the spoon forms a concave mirror... so the light is reflected back at different angles than their original direction. This results in a point called the focal point, where all the light reflected back from the mirror crosses each other. If you were closer to the spoon than the focal point, your image would appear right side up. However, if you are farther away than the focal point, then the light rays have crossed each other causing your image to be upside down.

Answer 3

It is upside down because the spoon is a concave surface. Light that strikes the surface will reflect at an angle, and at some point away from the surface (how far depends on the curvature of the spoon) called the focal point, it will flip upside down.

Answer 4

its actually right side up...you're just upside down

no...Light rays travel in a straight line until they hit something. A light ray comes straight back only when it hits an object dead on. If the surface of the object is slanted relative to the light, it will cause the light to be reflected at an angle. So, a spoon's surface is curved, both from top to bottom and side to side. And all the light that enters our eye does so in the same direction (we'll call it the horizontal direction). Light from our toes hits the top of the spoon and, because of it's 'downward' slant, gets redirected horizontally. And only light from our head gets reflected horizontally from the bottom of the spoon. Since what we see is WHERE the light came from, we see our toes above our head!

Answer 5

It's so because all the concave mirrors reflect the picture upside down when the object is further out of the focus.
For concave as well as convex mirrors there a imaginary spot called "focus" in which all the paralel rages unite. there are rules depending on the position of the object. The objects can be normally oriented, upside down, real, imaginary ecc.

Answer 6

coz the spoon is bent so the light bounces off the bottom of the spoon to your eyes and the top of the spoon to your chin making u look upside down. it is really just how the light reflects off the spoon

Answer 7

The spoon is a concave mirror. So, the laws of image formation that apply to the concave mirror apply.

Answer 8

Reflection of light in concave mirroroccurs as a reversed image. The lense in you eye projects it correctly ,your brain see it up right.

Could it be because you are known as a spoon faced shinanogan?.......
