What is the main purpose of a laser?
The main purpose of a laser is to focus electromagnetic radiation (light) on to a single point.
How a beam of laser light is different than the beam of light produced by a flashlight?
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb.
How is a laser different from other light?
A laser is different in three main ways: 1- The light emitted from a laser is monochromatic, that is, it only has one wavelength (color). Ordinary light on the other hand, is a combination of many different wavelengths (colors). 2- It is coherent, that is, the waves of light of the laser are in phase. Just like two sea waves when they are both at their maximum height, all waves of the light in a laser are exactly at the same amplitude, all time. 3- It is highly directional. Laser light is emitted as a narrow beam in a specific direction. Ordinary light coming from the sun, a light bulb or a candle is emitted in various directions from the source. Since laser rays are so concentrated they also have much more brilliance than rays from other sources.
Difference between white light and laser light?
White light is a mixture of many waves of different links called frequency, it's like musical instruments playing different notes, but the light from a laser contains waves of one light only which make a single color.
The main difference of the semiconductor lasers and gas lasers?
The main difference is the medium of the laser.
What is the main purpose of a laser?
The main purpose of a laser is to focus electromagnetic radiation (light) on to a single point.
What is laser spectroscopy the study of?
Laser spectroscopy studies the effects of lasers on molecules. The main purpose of laser spectroscopy is to learn more about the reactions of molecules to light, and how this can aid in development of light-sensitive technology.
What are the three main characteristics of Aves?
They fly
What type of laser treatments are available to treat acne?
There are three main types of laser treatments for acne. Blue light was the first to be approved, Infrared treats mild inflamed acne, and Photopneumatic therapy that removes excess oil from pores.

wolf dog and cat

What are the three main ingredints in photothinsesis?
the three main ingredients for photothensesis are light, oxygen and carbon dioxide.
White light is a combination of three main colours of light they are?
red blue green
What is the main source of light in a scene in a three point lighting system?
Key light
What is laser engraving?
Generally, laser engraving machine has three main parts: a laser, a controller, and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.
What are three main characteristics of a bureaucracy and why are they important?
hierarchial authority, job specialization formalized rules
