A common question from students is "How far can a laser's pointer travel?". A 1W blue laser can easily reach up to 450 miles , and is ideal for presentations. The beam can be directed in many directions, including at moving vehicles. But a high-power laser could spread its beam so far that it is unable to be seen from a vehicle. In such situations the use of a laser with a higher power can be employed.

The laser power of an object varies. A laser with a power of 200mW can be seen over a mile away. A red laser of 1000mW can be visible for ten miles away. Certain lasers have a shorter range. According to ScienceDaily.com the world's largest laser spans 270 km. It's important to know that a projectile or a 'laser' in space will produce light as long as it strikes something. A green laser however will only illuminate a small area of a room.

If you're worried about security, you may want to choose a laser pointer that is green. It's as bright as an 100-watt light bulb when viewed at three feet, however it's nearly as bright as a quarter moon when looking up from 40,000 feet. Laser pointers that are green, however isn't safe to use. Always choose an established brand. If you're not certain, read reviews and ask friends and family if they've had any accidents with these gadgets.

While lasers can travel far distances however, their range is very limited. This is because they can be too powerful for the distance they can be able to cover. It is recommended to store them in a sealed enclosure to prevent accidental spills. Also, while you're there don't forget to check the range for the range of laser. It's a great way to be safe and avoid an unsafe situation!

There are many different methods of determining the distance a laser pointer can travel. Distance to moon 238 miles, and it's possible to locate one with a power of 500mW. It's possible to use the 50mW laser, and it will be able to work as far as it's supposed to. Utilizing a laser with a power of 5mW can be dangerous and distracting.

Laser pointers are designed to function at a low power level. If you've got one that's a few thousand milliwatts and you are able to see it for up to 1 mile. If you're on the air, it might be impossible to see the laser pointer , unless it's directed at your eyes. However, if you're in middle of nowhere the light of the laser pointer can be observed far away.
