Why is the laser beam made of a light of a single colour?
The color of a beam of light is dependent on its wavelength. A laser will appear as one color because all the light being emitted from it is the same wavelength. This is also why lasers and laser pointers always have such a tight beam. By contrast, flashlights (which have much wider beams, and rely on mirrored interiors to amplify the light) have light at a variety of wavelengths, which is why the light is ultimately "colorless".
Why laser beam is narrow straightwhere as light from tube light is blury?
That's one of the properties necessary to consider a source of light as a laser source.The light rays in a laser are manipulated so as to make them coherent.
A laser produces light that is what?
Intensified.
How is laser light different from incandescent light?
The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.
Why does laser light visible in smoke?
yes,you should be able to...i think why dont you test it?
What is the difference between a laser and an ordinary light in terms of colors?
An ordinary light contains more than one colour. A laser is monochromatic.
Is this true or false laser light is one color because the light waves have the same wavelength?
True, however you mis-spell colour.
What is a laser light with holograph?
a laser light with a holograph is a laser light with holograph.
What is a laser formed out of?
It is formed of electromagnetic radiation - light, with only one wavelength, (one colour); highly directional and focused, that is, the rays of the light of a laser don't disperse much; and all the waves are moving in sinchrony, in phase.
What is the colour Blu-ray disc?
Any color ... the "blue" does not refer to the color of the disk but to the laser light that reads the disk.
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.
How many colors are in a laser beam?
A laser, by its very action of amplification of light, tends to be monochromatic. (one colour). But lasers may be made in several different colours depending on the materials used.
Do laser printers print in colour?
no
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
How do you chenge powder in laser printer?
The toner powder in a laser printer is sealed inside a toner cartridge, and it is the wholecartridge that is replaced. A mono laser has a single cartridge, while a colour laser will have a cartridge for each colour.
Which element forms with all other elements except heliumneon and argon?
Probably fluorine.
Is a laser artificial sunlight?
No. Laser light is artificial light, but it is not sunlight.
