Physics Help! Laws of Reflection...?

On the image. The light works exactly as it would if the object was actually behind the mirror at the distance it appears to be.

Someone posted the exact same set of questions a few days back, either here or on the physics page - you ought to be able to find the methods in the responses. Have a look.\n\n\nBest of Luck - Mike

do u mean speed? no, the magnitude is stillt he same but the direction is changed if and only if the mirror has a smooth surface. cause if it is not. there would be many angle of reflection

The speed that the reflection is moving at is near light speed (186,000 miles a second). The spot we see the reflected light coming from is different as the plane moves across the earth, regardless of how fast or slow the plane is moving.

Unless the reflective surface is perfect (which is impossible in the real world) the light will loose a little energy with each reflection (the mirror will heat up a little), and in a very short time the light will just get redder until it is merged into whatever infrared energy is inside the sphere.

The angle of reflection is equal to\nthe angle of incidence

y dont u do ur homework urself .ok heres abrief intro.\n\n1.see the level of frequency changes when beam of ultra violet light rays enter to one medium from another medium(to glass from air).\n\n2.when light undergoes refraction it frequency changes its speed acc. to the medium such as(glass,air and water)\n\n3.yes there will be,as light enters to one medium from another medium.

#1: It doesn't. The frequency of a beam of light remains constant regardless of the medium through which it travels, although the wavelength may change.\n#2: Absolutely nothing, for the same reason as #1.\n#3: Not for a mirror. The focal length of a mirror is determined by reflection, not refraction, and the angle of reflection is equal to the angle of incidence, regardless of the medium.\n#4: 1:1. The velocity of light does not depend on wavelength*\n\n*okay, for some materials the index of refraction, and therefore the speed of light in that material, depends slightly on wavelength, which is why a prism can be used to separate light into its various colors. However, the question did not specify a particular medium, so I assumed it meant in vacuum, where the velocities of all light rays are indeed the same.

A mirror reflects light.  Light from an object strikes the mirror and changes direction so that the angle of incidence equals the angle of reflection.  As a result, light appears to come from behind the mirror, at an apparent distance equal to the distance they are in front of the mirror.\n\nI see no connection to the Boognish.

First realize that since the beam is passing through something, reflection has nothing to do with it.  The only possible answer is the one that mentions refraction.

A mirror CAN make things look upside down.  Stand in front of a mirror and hold a book up so you're reading the cover.  Now, turn the book so the cover faces the mirror and you can see the book cover in the mirror.  Normally you would rotate the book about a vertical axis, THIS is when the left and right reversal takes place.  You could instead turn the book upside down.  Then the reflection of the cover WOULD be upside down, and not backwards.\n\nOther answers given:\nRefraction does not happen. Only reflection.  Refraction has to do with the bending of light when it goes from one medium (such as air) to another medium (such as water).  It has nothing to do with the question.\n\nBecause our eyes are next to each other.  Close one eye and prove to yourself that that answer is nonsense.\n\nAlthough it seems backwards its really not.  Prove this is wrong by holding a book to a mirror and trying to read it.

(1)mirrors reflect light because it has a shiny and reflective metal behind it.\n(2)camera lenses

Light can move in a few ways, all of which are rays.  Rays are striaght lines, and light can never curve (unless you are in a black hole, if that's the case....too bad for you) but it can be REFLECTED or REFRACTED.\n\nReflection is when a light ray bounces off of a surface and does so in predictable angles.  On a flat surface, the light relflects at an angle equal to that which struck the surface.  This is how a flat, or plane, mirror works (bathroom cabinet, dresser).  A rounded surface can magnify and distort an image by reflecting the light rays at different angles over its entire surface.  The law of reflection still holds true, but since the surface is irregular, the image reflected is not true to life (fun house mirrors, magnifying mirror for make-up or shaving).\n\nREFRACTION is the bending of light as it changes mediums and cause changes to images as well, such as when looking into an aquarium tank.  I know you didn't ask about this, but call it a bonus.

Say you shine a flashlight into a mirror. Then put a mirror behind the flashlight and remove the flashlight. Given that the 2 mirrors are exactly parallel, will the light just bounce back and forth forever? No - the light travels in waves and each time it reflects back, some of the light is not hitting the mirror exactly at 90 degrees and is reflected off on an angle. The light will reflect away and eventually dissipate completely. \nIf you try to trap light in a box, as it bounces off the walls inside, it will dissipate into energy (heat). The temperature of the inside of the box will raise - but just infintestimly so.\nRemember all of this will take place at the speed of light.

Refracted light rays bend toward the normal when the material being entered has a higher index of refraction then the material you are coming from.  Reflected light behaves according to total internal reflection, and bounces off the surface at the same angle that it approached at, much like skipping a stone off a lake's surface.  Check out snell's law on wikipedia for more.

you either need more information, or this is a trivial problem. \n\ni am assuming the two surfaces of the glass are parallel to each other, so it's not a prism or lens, but a thin flat plate.\n\ntreating it very simply, you could argue that energy is conserved, so the irradiance (which is energy per second per square meter) must be conserved.  the speed of light is fixed in air, so the "per second" part is fixed too.  if the glass surfaces are not angled with respect to each other, then the light leaves the glass taking up the same area that it went in with.  this means the irradiances are the same.\n\nthis is a simplistic physical model, though.  realistically, you will get some reflection at the air-glass interface, reflection at the glass-air interface, and some absorption (both in the air and in the glass).  you need a lot more details about the problem to say anything meaningful though.
