A mirror has no effect on the speed of light, but it has a radical effect on the
velocity of the wavefront, because it reverses the direction of the normal
component of the velocity.

What is the speed of the image if an object is fixed in front of a plane mirror and the mirror is moved with a speed v?
For a flat mirror (front surface) with the object having an angle of incidence with the mirror of 45 degrees, and the image measured perpendicular to the object, the speed is v. A side note, using a laser pointer, a spinning mirror, a meter stick, a ruler, and a sheet of paper, and measured, with a lab partner, the speed of light within 10%, in the space of a square meter. This was so many years ago, that the speed of light was much less than it is today.
How does the shape of a plane effect the speed?
yes but i dont know how....
What is the speed of light in zero gravity?
Gravity does not effect speed of light ,so velocity is constant. Even if it effect the effect is negligible. So in short answer is 3*108ms-1 -Thunder
What does light produce in a photoelectric effect?
When the light combine with the speed in a photoelectric effect it produces a picture of the object.
How did a spinning octagonal mirror help michelson calculate the time that light took to make the round trip to the distact mountain?
He adjusted the mirror so that the beam of light would reflect back into his lens. As the mirror was spinning around (1/8 of rotation) it shot short burst of light off the mountain mirror and into the spinning octagonal mirror, helping him calculate speed of light at around 300,000 km/s.

How much faster does the speed of light travel than a plane?
The speed of light is approximately 186,282 miles per second, whereas the average speed of a commercial jet is around 500 miles per hour. This means that the speed of light is over 670 million times faster than a plane.
Why is light's speed the same after emerging through a glass pane?
the speed of light decreases when it enter the plane and when it comes out of the plane it the speed again increases as there i sdifference in th refractive index and the interface of the glass plane is parallel
What is frequency of rotating mirror in speed of light?
very fast
How does the shape of a plane effect the speed?
yes but i dont know how....
If a plane is traveling at the speed of light and turns on its head ligths will the light be even with the plane?
A plane CAN'T travel at the speed of light.If a hypothetical super-spacecraft goes very close to the speed of light, and a beam of light is emitted from the spacecraft in the "forward" direction, the speed of the beam of light from the spacecraft would be measured to be the so-called "speed of light", i.e., 300 million meters per second. Note that the speed of this beam of light, as measured from Earth, would ALSO be 300 million meters per second. This seems weird, or even impossible, but it has been confirmed by the famous Michelson-Morley experiment, and explained by the Special Theory of Relativity.
If a plane is traveling at the speed of light and you walk to the bathroom on that plane are you faster than the speed of light?
The answer is NO. The speed of light is constant in our space-time from all reference frames. This means that going faster than the speed of light is not possible. Within a moving reference "plane", you would still see light travel across the interior, travelling at the standard rate of 300,000 km/sec. For an observer outside the plane, the speed would still appear as that constant due to time dilation.(see related link)
If you could travel at the speed of light and you looked in a mirror would you see your reflection?
That would depend on your speed relative to the mirror. If you were holding it in front of you, yes. If it was stationary and you were passing it, no.
Does gas effect the speed of light?
Yes it does
When train is travell with speed of light nd we put a mirror in front of me then what will image formed?
An object such as a train simply CANNOT travel at the speed of light. You can investigate what happens when it moves close to the speed of light.
What is the effect of refractive index on speed of MW?
Exactly the same as its effect on the speed of light, since light and MW are the same identical physical phenomenon.
What is the effect on the speed of light when temperatures rise in the medium?
When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.
