Homework Answer on Laser vs. X-ray
The word laser denotes the acronym light amplification by stimulated emission of radiation. According to Zeidler (n.p.), laser is a combination of two photons brought together to create a laser beam.By bringing the two photons of light together, a laser beam is created capable of doing a number of things, such as measure speed (as used by police) and read or write electromagnetic information as used in the CD players and computer optical disk drives.
In looking at laser wavelengths, it is important to note that their wavelengths have variations, which determine the visibility of the said wavelengths, all measured in nanometers. The variations of wavelengths include ultraviolent light within 100-400 visible spectrums; visible light, 400-750; and infrared that range between 750 nanometers to 1 mm. Lasers have different laser models, but it is possible to customize the laser wavelengths.
As a monochromatic light, the typical laser wavelength is 632.8nm. While that is the typical wavelength for a lacer, customization of the lasers allows a wide range of wavelength for the lasers within the visible light wavelength of between 380 and 740 nanometers.For the frequency and bandwidth, lasers can be custom fitted according to the use of the beam. Commercial lasers operate within the 1500MHz frequency. For such lasers, the bandwidth lies between 30 and 60 nanometers.
