Before you purchase a laser pointer online, you may find yourself wondering how far the beam can be seen. If you’re not familiar with different aspects of laser technology, this question might not have a clear answer. You may be wondering why do lasers look grainy sometimes and if that’s a bad sign of quality. …
A laser looks grainy to you because of the wave nature of light or interference. Light coming into your eye from a laser does not exhibit speckle. This ‘grainy look’ or what’s referred to scientifically as Speckle occurs because the laser light is temporally coherent and is scattered from a random surface. The random surface …
The reason why lasers bounce off of mirrors has to do with the laws of reflection and refraction. The law of reflection states that when light reflects off a surface, it changes its direction by an angle equal to the one at which it hits the surface. For example, if a beam of light hits …
People are coming up with different technologies all with the aim of easing the whole human operation speed. Today the LIDAR and the LASER technology have become a go for and many people are talking about the opportunities that these technologies are offering and the ones they will offer in the future. With the definition …
