Bookmark or Share- Why are mirror images flipped horizontally but not vertically?Mirror does nothing apart from inverting the Z-axis, as Feynman said. Each point on your body that is facing the mirror will remain with the same X and Y coordinates(or to say in simple language, image of each point is right in front of the actual point). Mirror doesn't differentiate any points as in such.
- Are infinite reflections between two mirrors really infinite?If you place two mirrors with a 1-meter distance and assuming the light is attached on top of one mirror: 3ns/meter => 333 million bounce/second => 166 million images per mirror per second. So, if you will wait 1 minute => 9.9 billion images. To get an infinite number of images, you need to wait for an infinite time (assuming no loss during ...
- visible light - Why does your reflection suddenly turn upside down ...When you are farther away from the mirror than the focal point a real image is formed between the mirror and it's focal point. This image is inverted. When you get closer to the mirror than the focal point a virtual image is formed behind the mirror and this image is not inverted. That's why the image flips as you get closer.
- Real image formation by a plane mirror - Physics Stack ExchangeThe lower middle image shows us how a mirror takes real object and generates virtual image. Finally, on the bottom image, we see a two component system composed of 1) converging lens and 2) a mirror. The mirror is a distance of $3f/2$ to the right of the lens.
- optics - Why does sunset over a body of water cause a path of light ...Now angle the mirror a bit to the side (rotate along an axis oriented along the line between you and the screen). Now your "waves" are not aligned with your "shore". But you can still see the screen (may require a bit of an inclination of the mirror rotating around a horizontal axis perpendicular to the previous one).
