A plane mirror is a mirror with a flat reflective surface. [ 1 ] [ 2 ] For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. [ 3 ] The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).
Thus reflection is a reversal of the coordinate axis perpendicular to the mirror's surface. Although a plane mirror reverses an object only in the direction normal to the mirror surface, this turns the entire three-dimensional image seen in the mirror inside-out, so there is a perception of a left-right reversal. Hence, the reversal is somewhat ...
By using two parabolic cylindric mirrors and one plane mirror, the image of the background is directed around an object, making the object itself invisible - at least from two sides. Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible (literally, "not visible").
The image in a flat mirror has these features: It is the same distance behind the mirror as the object is in front. It is the same size as the object. It is the right way up (erect). It is reversed. It is virtual, meaning that the image appears to be behind the mirror, and cannot be projected onto a screen.
The image in a plane mirror is not magnified (that is, the image is the same size as the object) and appears to be as far behind the mirror as the object is in front of the mirror. A diverging lens (one that is thicker at the edges than the middle) or a concave mirror forms a virtual image. Such an image is reduced in size when compared to the ...
The science fiction computer game Space Rogue featured the use of technologically harnessed wormholes called "Malir gates" as mechanisms for interstellar travel. Navigation through the space within wormholes was a part of gameplay and had its own perils.
My Science Project: Jonathan R. Betuel Michael and Ellie break into a military junkyard to find a science project. They find an orb that dangerously bends time and have to stop it to save the world. 1985 The Blue Yonder: Mark Rossman An 11-year-old goes back in time to prevent his grandfather from making a fatal plane flight across the Atlantic.
Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
