The rough light from the green laser pointer
The laser distance is not without its negative effects. The high powered laser pointer beam is disturbed by laser noise, stray light, and speckle results. Many ambitions may also have different reflection or scattering characteristics, which may lead to inaccurate measurements. Instruments designed to measure objects at very long distances can be annoying for people who are not wearing suitable goggles. Measuring long distances with lasers in extremely hot or smoky areas is tricky because these conditions will diffuse the beam.

Let's spend a little more time in physics class: the existence of lasers is attributed to electrons. You may remember that electrons are these active particles, which hover around the atom to form its "shell".Some electrons have the ability to absorb energy from outdoor sources and bounce back to higher energy orbits, at least temporarily. Young people, the electrons quickly return to their normal orbits and release the extra energy they use, which then creates ripples in the atomic backyard.
