Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.
How are a laser beam and a flashlight beam alike and different?
A LASER, or Light Amplification by Simulated Emission of Radiation, and is made by causing a particular substance to emit photons, almost all of which are one wavelength. A flashlight, however, uses a light bulb, which emits light due to the filaments, and will spread out. Both, however, are forms of light.
Is monochromatic light is a ultra violet light?
Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
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 is a light bulb in 1 shape?
I can assure you that light bulbs come in many different shapes.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
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.
What kind of electronic has two legs and gives out light?
An LED, laser, or light bulb.

Can you name three artificial light source?

What technologies are in a light bulb?
There are different era of technology of a light bulb.

How is a laser light different from a regular light?
laser light has a constant wavelength whereas regular light is made up of many wavelengths
What is an example of optics?
Some examples are Light bulb, fiber optics, laser surgury intruments.
How are the colors of the lights changed at a laser light show at the concert?
They are changed by a lens in the light machine, They have a white bulb and change the slides to pass through the tiny holes to make it seem as if it was a laser.
What are Types of optical technology?
Some examples are Light bulb, fiber optics, laser surgury intruments.
