if you're walking towards a mirror at 1m/s, how fast are you approaching your image?

1m/s physically you are walking towards a stationary object that is reflecing your image, as such you are walking towards it at the steady 1m/s.\n\nIf not that then you are both approaching a common point at 1 m/s so you combine your velocities to get 2 m/s.  but that's semantic bullcrap\n\nYou could get really technical and add in the fact that the photons are travelling back at you at the speed of light but that's just stupid.

IF YOU WERE GOING AT THE SPEED OF A BULLET,YOU WOULD BE RIGHT NEXT TO IT AT SPEED O. THE SAME WITH LIGHT, IF YOU WERE GOING THE SPEED OF LIGHT IN YOUR CAR (LET'S SAY )YOU WOULD SEE THE LIGHT ON,BUT TO SEE THE LIGHT OFF YOU MUST BE GOING FASTER THAN THE SPEED OF LIGHT.SO THEN YOU SEE THE LIGHT ON AT THE SAME SPEED THE CAR IS GOING.

about 186,000 miles per second.  With our present technology, it would take hundreds of thousands of years. At the speed of light, it would only take thousands of years.

The speed of sound: 340.29 m / s

light travels at 186,000 miles per second, the earth is 25,000 miles around....\n\n25000/186000= 0.1344 seconds

it depends how fast u go. lol

You would be in a different universe than you are now, because the laws of our universe say that a massive object can't go faster than the speed of light (or even as fast).\n\nAlso, if you changed the question to "...1 mile per hour less than the speed of light", you would have to specify "relative to ..." (what?)  And then you would have to say, what would happen as observed by (whom?).  In this question, relative to you, the headlights would turn on and you would be able to see things 186,000 miles ahead of you (as you measure miles) within 1 second (as you measured seconds) .  Relative to the observer that thought you were moving 1 mile per hour less than the speed of light - assuming you were moving toward the observer - you would get to him or her just a tiny fraction of a second after he/she saw the headlights turned on.  Your measurement of the speed of light would be consistent, but your measurments of time and distance would be very different.

no, the focal lenght is the property of the mirror, not of the medium in what is situated.\nthe focal lenght = mirror radius / 2

the opposite of the speed of light :)

The speed of light. 186,000 miles per second.

3 ft if it is the person who needs to see the complete image, because however distant the mirror, the virtual image will always be twice the distance of the mirror from the observer, and the mirror will work like an aperture.\n\nIf someone else wants to see an object in the mirror, the size does not matter as long as the distance of the observer to the observed person relates to the mirror "aperture".

(m)\n\nThe speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8  km·h-1, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour). This value is denoted by the letter c, reputedly from the Latin celeritas, "speed", and also known as Einstein's constant. Note that this speed is a definition, not a measurement, since the fundamental SI unit of distance, the metre, has been defined since 1983 in terms of the speed of light—one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. The speed of light through a transparent medium (that is, not in vacuum) is less than c; the ratio of c to this speed is called the refractive index of the medium.

You have answered your question.\n Human eye can comprehend 10 images per second. More than that one cannot comprehend.\n\nTherfore, if film speed is 10 frames per second, every one can count the no of frames on seeing cinema. THE ILLUSION OF CONTINUITY will be lost and will only view a slideshow and not a motion picture.\n\nIf the flasing  rate is fast the flicker is not observed and the flashes appear continuous.\n\nIn earlier films , the speed used was 16 frames per second to obtain this illusion.\nIn these films one can perceive the lack of smoothness. \n\nThese effects are very much reduced  when 24 frames per second is used.\n\nIf we move a glowing match stick to and fro slowly we can follow the movement. If it is done fast  in a circular  motion we can perceive only a circle of light.

One example to measure the speed of red light is to use equipment that includes a LED (light-emitting diode) that emits a regular series of pulses of red light that are only 20 nanoseconds in duration.\n\n    (A nanosecond is one-billionth of a second or 1/1,000,000,000 second. It is also written as 10-9 seconds, 10^-9 or 1e-9, where the -9 indicates the number of zeros in the denominator.)\n\nThat means the pulse of light blinks on for 20 billionths of a second or 20/1,000,000,000 second and blinks 40,000 times per second. Having such a short pulse allows the scientist to measure the difference in time it takes to travel two different paths. If the duration was longer, the distance traveled would have to be longer.\n\nBy splitting the light beam with a half-silvered mirror, one beam travels to a mirror 10 meters away and then back to a photodiode detector. The other beam is reflected off a mirror only a few centimeters away. The time difference for the two beams is about 67 nanoseconds, which can be displayed on a regular dual beam oscilloscope.\n\nThe total distance the light travels is 20 meters, which equals 0.02 kilometer (20/1000).\n\nThe speed of light is then:\n\nc = 0.02 kilometers / 67*10-9 seconds = 298,500 kilometers per second\n\nThis is a fairly accurate reading and pretty close to the actual speed of 299,792 km/s.

Time would conquer you. considering that to all outside observers you would vanish. From your viewpoint the entire universe would cease to exist even if you were to slow down now you would find yourself in a limitless and absolute void with no reference. You would be in absolute solitude.\n\nTraveling at relativistic speeds (fractions of the speed of light) distorts time relative to outside observers. time/the inverse of the factor of c.\n\nIf you were to travel at 1/1,000,000,000 the speed of light 1 second to an outside observer would only be .999999999 seconds to you.\nIf you were to travel at 1/2 the speed of light 1 second would be .5 seconds\n\nI believe that this maybe one of the thoughts that lead Einstien to the statement "Time is an illusion, although persistent, still just an illusion.
