touqra said:Why is it that a mirror reflection only exchange the notion of left-right but not up-down ? I mean if I were to stand in front of a mirror, my mirror image exchanges my left hand with the left, but not my head with my legs.
krab said:Actually, it does neither; it reverses front-back.
A mirror reflection is when light bounces off a smooth surface, such as a mirror, and creates a virtual image of an object that appears to be the same size and shape as the original object, but reversed from left to right.
A mirror reflection reverses left and right because light travels in a straight line and reflects off the mirror's smooth surface at the same angle that it hits. This causes the image to appear flipped horizontally.
A mirror reflection does not affect depth perception because the distance between the observer and the virtual image in the mirror is the same as the distance between the observer and the actual object. However, if the observer moves to a different position, the depth perception of the image may appear to change.
Yes, a mirror reflection can be manipulated by changing the angle at which the light hits the mirror's surface. This can create distorted or elongated images in the reflection.
No, not all mirror reflections are the same. The type of reflection can depend on the angle of incidence, the smoothness of the mirror's surface, and the material of the mirror. For example, a concave mirror may produce a different reflection than a flat mirror.
