Is a laser an optical device?
it means things like eyes, glasses and the laser used to read dvds
What part of the body will be damaged most easily by a laser beam?
The eyes are the most vulnerable part of the body to be damaged by a laser beam. The intense concentration of light can cause serious harm to the delicate tissues of the eyes, leading to vision loss or even permanent blindness. It is crucial to use appropriate eye protection when working with lasers or being exposed to laser beams.
XmcmxjWhy do you only see laser beams through dust or through cloudy water?
The reason we can only see lasers through dust or cloudy water is because our eye can only see light that enters directly into them. When a laser travels across our plane of vision the laser beam is traveling in a straight line, but when it hits the small particles of dust that light is being reflected in an infinite number of directions. A portion of those reflected light rays enter our eyes resulting in what appears to be a laser beam.
What is an important rule when dealing with a laser?
An important rule is that never point laser to anyones the ray is too strong Especially to the eyes. Vision would get damaged permanently.
How do you explain the characteristics of laser beam?
Laser beams are normally characterized as focused (the beam size enlarges slowly with distance), intense (don't look into a laser beam), and mono-energetic (single-color light). What is laser? -- laser stands for "light amplification by stimulated emission of radiation." What is being stimulated in laser? -- gas, solid-state, semiconductor, dye, chemical etc. Each type of laser has its own characteristics and pros and cons. The origin of laser radiation in a gas laser -- take a gas laser, for example. Argon gas is trapped inside a pressurized tube (low pressure to be exact). The tube's curved wall is coated with metal for reflection. Two flat mirrors are situated at each end of the long cylinder. Energy, in the order of kilowatts, is supplied to ionize the Argon gas. The excited Argon atoms will relax to release light in a very narrow spectrum, in the order of Watts -- very inefficient indeed. The mirrors and shiny curved wall are to keep the light generated to be trapped inside the tube intentionally, so that the lasing action can be amplified. The mirror at the "business" end has a small opening to allow light to escape. Hence the exiting laser beam is more or less uni-directional (focused). The light coming out of an Argon gas ranges from red to UV, but a filter at the exit can narrow the spectrum further to mono-chromatic. The filtered single-frequency light has little dispersion (photons will be traveling at about the same speed and few interference). The light is so intense and concentrated (~ 1 W over a beam size of 0.1 cm^2) that looking into a laser beam is detrimental to your eyes. Looking into a key-chain laser is not advisable either.

Yes but is would be very hard. I wouldnt be to worried

1 to 5% experience complications. Light sensitivity, dry eyes, glared vision, etc.

Of course.
How can flashlights harm?
a flashlight could be a weapon if with crown, and if with laser light it is harmful for eyes. so use it accoring manual or basic principles.
