How does the light from the flash of a speed camera get back to the camera to produce the photo?
Things that you are photographing reflect it.
How do you know if you got a speeding ticket if the camera didnt flash and the boot were the camera sits is open?
Notification of speed camera tickets is usually through the mail.
How does a speed camera van work?
Police are able to utilise a variety of handheld laser and radar equipment to calculate the speed of oncoming vehicles. Once the speed is pre-determined, they are able to apprehend any law breaking motorists almost straight away with on the spot ticketing. Mobile vans are exactly the same - Some are manned vehicles and some are "automated" with speed tracking equipment that can be left at the side of the road. Quite sneaky!

What speed will a speed camera flash at?
it depends what speed the speed limit is at, usually 10 km/h faster, that way not too much but can still fine plenty
When you are entering a lane how many feet must you be from an oncoming vehicle to make it safely?
That's going to depend on your speed and the speed of the oncoming vehicle. Plus, we're pretty sure that it also depends on the speed of the guy you're trying to pass.
Is it illegal in the state of Virginia to flash oncoming drivers of a speed trap?
No it's not, though in some other states it is. However, if one chose to try, a great 1st Amendment argument could be made for your right to do so.
Does THE ability to judge speed and distance of oncoming vehicles change as we get older?
Not exactly - Your perception of, and ability to judge, speed increases when you become more experienced, if you've been driving for 30 years, you'll be able to gauge speed/distance better than someone who's been driving for 3 years.
How can you prove that when making a left turn the oncoming car was speeding and thus resulted in an accident?
It wouldn't matter if the oncoming car was speeding. When making a left turn you must always yield to oncoming traffic regardless of their speed.
Can speed camera take photo from opposite side?
A camera can only take a photograph from where it is located. Two cameras together (or two exposures from different positions) can make a stereographic image (which can give the illusion of depth (3D) Some speed traps have cameras on both the oncoming and other side and so can take pictures of the receding vehicle (not yet in Sweden where I am located now though)
Why in Olympus digital camera shakes while clicking without flash?
This is something that can happen with any camera and is not specific just to Olympus. To understand the relationship between camera shake when using a camera with or without flash, you first need to understand the basics of shutter speed, camera metering and flash. The shutter speed in how fast your camera closes the shutter when snapping a picture. Fast shutter speeds of 1/160th of a second and higher are usually required for freezing action. Even at 1/160th, you may get some blurry images depending on what is being photographed. Also, a faster shutter speed allows less light in through the lens and slower more light. This speed needs to be adjusted to capture the proper balance of light for the photograph called Exposure. Most people that use a point and shoot camera are using the automatic modes, such as P(Program). In these modes, the camera is using it's internal meter to control how fast the shutter needs to be for a proper exposure. In a low light situation, the shutter will be slow. Since the shutter is open longer, this will cause camera shake due to the small variations and shakes you are making with your hands. It may not be noticeable to you, but it is to your camera's sensor. So why does it go away when using flash? The answer is simple. Flash happens a fractions of a second... much faster than your camera's shutter. This instant light pulse reaches your subject before the ambient light has time to register on your camera's sensor. Since this light information is seen immediately a so briefly, it freezes your subject in place. Even with a longer exposure, the illuminated subject should stay frozen while ambient light fills the rest of the frame. A trick you can try is setting your camera to a manual exposure and set the shutter speed to 2 or 3 seconds. Take a flash photo of someone, but move the camera around after the flash. Your subject should be relatively frozen while the rest of the frame is blurry or shaky.
On a manually-operated camera exposures can be made or manipulated with the shutter speed and the aperture one of these controls the output of the flash do you know which one?
The answer is Aperture. The Shutter Speed does not affect Flash output. You can prove this by setting up a camera with a flash in a room where you can control the lighting. Photograph an object in the room until you determine the best flash exposure...such as F 5.6, F 8, etc. Now that you know the F stop (aperture) that allows the proper amount of flash, turn off the room lights so that there is virtually no ambient light in the room. Leaving your camera set to the correct aperture (F stop), take different exposures by changing the shutter speed each time while not changing the aperture. You will see for yourself that the flash exposure is the same with each exposure even if you try one shutter speed at 1/60 and another at 1/2 second. The shutter speeds would only make a difference in the overall exposure if there was existing ambient light...then the exposure would become light or darker depending on the shutter speed. With a slower shutter speed the scene would be brighter as more ambient light was taken in, but the shutter speed did not affect the flash, only the ambient light.
Is it legal to flash oncoming drivers of a speed trap?
Different states may have different laws. Where I live it is not illegal. But remember this: A speed trap is only out to catch those that are breaking the law. If you condone people breaking the law then by all means go ahead and warn them, support a criminal. The person that you flash to slow down may be someone that will speed up after they pass the officer and kill themselves or another. It says "Speed Limit." not "speed suggestion." As a first responder I have seen too many people hurt or killed because of not obeying the speed limit.
