It is extremely coherent and focussed, not scattered like, say a light bulb.
Yes, looking at a laser can be more dangerous than looking at a light bulb of the same intensity. This is because lasers emit highly concentrated, powerful beams of light that can cause eye damage much more quickly than the diffused light from a light bulb.
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.
Light waves originate from a light source, such as the sun, a light bulb, or a laser. When an object absorbs energy, it can emit photons, which are the elementary particles of light that travel as electromagnetic waves.
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.
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'.
No. Laser light is coherent. Light bulb light is not.
An LED, laser, or light bulb.
Yes, looking at a laser can be more dangerous than looking at a light bulb of the same intensity. This is because lasers emit highly concentrated, powerful beams of light that can cause eye damage much more quickly than the diffused light from a light bulb.
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.
There are different era of technology of a light bulb.
A laser beam has more energy than a light bulb because it is a concentrated beam of coherent light, meaning the light waves are all in sync and traveling in the same direction. This coherence allows the laser beam to deliver its energy more efficiently and at higher intensities compared to the dispersed light emitted by a light bulb.
laser light has a constant wavelength whereas regular light is made up of many wavelengths
Some examples are Light bulb, fiber optics, laser surgury intruments.
A light beam is a broad spectrum of electromagnetic radiation emitted by a source like the sun or a light bulb, while a laser beam is a focused, coherent beam of light produced by stimulated emission of radiation. Laser beams are more intense, monochromatic, and directional compared to regular light beams.
Laser light is different from visible light in several ways. Laser light is monochromatic, meaning it consists of a single color or wavelength, while visible light contains a range of colors. Laser light is also coherent, meaning its waves are in sync and travel in a straight line, unlike visible light which scatters in different directions. Additionally, laser light is intense and focused, making it useful for various applications such as cutting, welding, and medical procedures.
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.
