What do lasers emit?
Lasers emit light, high intensity light that only faces one way (the direction the light is pointed at). cheap lasers are less accurate when it comes to shining light on one spot.
Is light from a yellow laser safer than red or green lasers?
All lasers can be dangerous, but with a yellow laser the light doesn't remain on like most other lasers. With all lasers there is a high and low end of the spectrum.
Where can one purchase lasers of different wavelengths?
Lasers of different wavelengths can be purchased from many sites online, such as Lexel Laser, and Wicked Lasers. Be sure to check the legality of the lasers in your country or risk losing them at customs.
How many different classes of lasers are there?
Seven
What type of light does a light bulb produce?
they produce protons and electrons they are collition then the light produce and heat produce
How is laser different from other light?
Lasers have only one colour & are focused on an area while ordinary light is made of the colours you see in a rainbow and fan out.
Why are lasers different from other kinds of light?
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
How is ultraviolet light different from ordinary light?
It is not visible by the naked eye.
What do lasers emit?
Lasers emit light, high intensity light that only faces one way (the direction the light is pointed at). cheap lasers are less accurate when it comes to shining light on one spot.
Do lasers emit gamma rays?
No. Lasers produce coherent light.
Is light from a yellow laser safer than red or green lasers?
All lasers can be dangerous, but with a yellow laser the light doesn't remain on like most other lasers. With all lasers there is a high and low end of the spectrum.
How do you perform frequency signal processing on 3d laser scanner images so that the colours match those of an ordinary camera photograph?
That would be hard, if not impossible. Lasers work purely by reflection back from an object. Colour information comes from the frequency of light. Your detection equipment would have to simultaneously detect the laser light and the different frequencies of light.
Do optical mice have lasers in them?
No optical mice do not have lasers in them, they use LED's (light emmiting diodes).
Where can one purchase lasers of different wavelengths?
Lasers of different wavelengths can be purchased from many sites online, such as Lexel Laser, and Wicked Lasers. Be sure to check the legality of the lasers in your country or risk losing them at customs.
What are some uses for optical lasers?
Optical lasers, also known as laser optics, are beams of light that come in many different strengths and possible uses. Modern computer mice use lasers to detect movement. Video game systems and DVD players use lasers to access discs. More powerful lasers are used for surgery and in laboratories as tools for experiments.
Is flashlight's light is straight?
no.. but a lasers is! and their fun
