How long does it take for light to produce a reflection off a mirror?

Light travels at about 186,000 miles/second... If the mirror is 3 ft away, the light has to travel 6 ft... you do the math.

How is reflection of light used in fiber optic?
total internal reflection is used in fibre optic cables as it allows for light signals to be sent across literally as long as you want. the light is never lost and can pass through stations in which the light strikes certain triggers which will produce a message allowing for the fast delivery of messages across long distances.

How did you ever find out the speed of light?
I Think they put lots of mirrors and shone a light and timed how long it took to bounce off each mirror with a computer.
How do you make toast with only a mirror and a pice of tin foil?
You wrap the piece of bread in a piece of foil. You can also leave a mirror a few feet away if the reflection is on the foil! I'm not sure how long that would take though!
If you put a giant mirror far out into space could you see into the past by observing the mirror?
Theoretically you could, but don't go shopping for giant mirrors any time soon. You might be thinking that if we place a large enough mirror far enough away that we could somehow see into our own past-- that is, the past relative to the people placing the mirror. In order for us to see our own past in the mirror, the mirror must already have been put in place at an enormous distance long, long ago, so that the light we see reflected in the mirror will have had its origin on earth at the distant past time that we would like to observe. Not doable. However, theoretical physicists and other scientists are already outlining not-totally-outlandish scenarios where travel through time may be possible in some circumstances. The outlining and the necessary engineering are probably going to be separated by many generations before there is any practical demonstration. Much more useful is the reality that the light we now observe from distant stars started its journey from the star as long ago as millions or even billions of years. Interestingly, from the point of view of the photons themselves, the trip is instantaneous.

How is the Law of reflection used in everyday life and in science?
The Law of Reflection is not only used in everyday life, but it can be used in pool. when you want to get the ball n the hole you can bounce it off of the edge as the "mirror". it is used everywhere as long as there is light and a mirror. It basically states that the angle of incidence should be the same as the angle of reflection. For example, your reflection. When you see it on an angle, your reflection is on an angle aswell, just on the other side of the normal (the 90 degrees line). You see it at exactly the same angle as the angle you are looking into the mirror at. It's used in science because it explains how light reflects off mirrors and how reflection occurs off convex and concave mirrors aswell.

What angle does a light ray reflect off a mirror?
the same angle with which it (the incident ray) hits the mirror surface. this physical law is known by the formula α =β.there´s a simple way to prove it: look into a (palin) mirror and ask someone else to look into the same mirror - preferrably from another distance. as long as you can see their reflection they should be able yo see yours and vice versa.
What kind of light bulb is used in the type of bathroom light fixtures that is a row of round lights on top of a mirror?
On lighted vanity mirrors you want to use a vanity mirror light bulb. The bulb is very round where the light is produced and is not very long.
What happens when you stare at a mirror to long?
Prolonged staring at a mirror can lead to a psychological phenomenon called the Troxler effect, where peripheral objects fade away. This can sometimes result in visual distortions or hallucinations where your own reflection may appear distorted or even start to change. However, these effects are temporary and can be reduced by taking breaks or refocusing your gaze.
What is in strobe lights?
A light bulb and a mirror and there is a gas inside called Xenon. Xenon allows for the very high intensity light and is long lasting.
Why doesn't moon shine as bright as the sun?
the moons light is reflected from the suns rays from a long distance like a mirror and a light you try it for yourself
How long will a dog spend barking at his reflection?
Untill he's to beat up from bumping into the mirror. So when he's too beat up and hurthe will stop. Or when he grows out of it just like our dog.

Can a pinwheel produce enough energy to give to a Christmas light bulb?
No, unless you hook it up electronically then it will probably not produce enough energy to light it up as bright or as long as and outlet.
