A laser is "concentrated light" in that its light of pretty much one frequency and focused in a tight beam. And if this light is directed into someone's eyes, damage to the retina can result. In higher power lasers, we find applications where they can inscribe diamonds or cut all kinds of things, including metal. If a laser beam can cut through a thick metal plate, it can cut through flesh with ease. A laser this powerful could take off a limb. Directed at the eye, it would destroy the eye in an instant. Spaces where lasers are being used require that warning signs be posted and that individuals working there wear appropriate eye protection. Divergence from safety procedures can result in serious injury.

Why laser beam is narrow straightwhere as light from tube light is blury?
A laser beam is a coherent light source that emits a narrow beam of light due to the alignment of its waves. In contrast, light from a tube light is incoherent and emits light in all directions, resulting in a blurry appearance. The difference in coherence and directionality between laser light and tube light accounts for their distinct characteristics.
What is special about laser light that makes it so useful compared to ordinary light from a light bulb?
Laser is non diverging one and monochromatic. It is coherent and hence highly intense. So laser could be sent even to reach moon's surface and get it back reflected. So distance of astronomical objects could be found.
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.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
Why do light microscopes use light?
so that when you want to see what the thing that your looking at is clear and you can see it and so it wont be dull or dark ...
Is it dangerous to use a boombox if the cd lid is broken(Will the laser blind me)?
The laser won't blind you, as the CD will cover it when in use. However, the laser can be dangerous for your eyes so be careful.
Why laser moves in narrow parallel beam of light?
Because a laser is just concentrated light, so it is thin from being concentrated.
What do you call a beam of light so powerful that it can cut through light?
A laser. Laser beams are intense and concentrated beams of light that have the ability to cut through various materials, including other light sources.
A highly concentrated beam of light is called what?
Laser

What do you call a bcam of light so powerful it can cut through metal?
laser
What is so special about the light from a laser?
it's monochromatic(all exactly the same wavelength) and every photon is in phase with all of the others(so, unlike ordinary light, all of the waves travel with the same wave shape) and it's a parallel beam, so the light doesn't diverge this means a 25 watt laser can cut through steel while an 80 watt light bulb can't it also means a 25 milliwatt laser leaves a brighter spot of light than an 80 watt light bulb(you can see the laser in the normal light) it also enables you to make a hologram it allows for lasersurgery
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.

What sends out a narrow intense beam of light?
Well... Most LEDs, Light Emitting Diodes, have a very narrow wavelength span, so they'd fit part of your question. However, they're not always that intense. So you're probably asking about a LASER.
What do you call a beam of light so powerful it can cut threw metal?
Laser Beam
