Sonic the Hedgehog is the title character of Sega's flagship video game franchise, who first appeared in 1991 in his first game for the Sega Genesis console (also known as the Mega Drive outside of North America).
When this beam is reï¬ected back to the laser unit, the unit provides a speed reading. Because of the narrow beams, laser units are hand-held, and can only be used from a stationary position.Common laser errors Both human error and the nature of laser light contribute to errors. For example, laser can only be used at a distance of a thousand feet. This does not give much time for aiming or vehicle identiï¬cation. Environmental and usage conditions also aï¬ect laser. Rain, fog, and snow can lead to false readings, as can reï¬ections of laser light from highway structures and other vehicles. As with any complex electronic device, there can be technical malfunctions and miscalibrations.
Laser light is monochromatic, directional, and coherent Monochromatic: The light emitted from a laser is monochromatic, that is, it is of one wavelength (color).In contrast, ordinary white light is a combination of many different wavelengths (colors).Directional: Lasers emit light that is highly directional.hat is the only characteristic of laser light. Ordinary light has a bunch of light waves where the timing of the waves has no relationship from wave to wave, so it is not coherent. Let me touch on why what other people have said is not right.
