What's the wavelength of the light emitted by the laser?
The wavelength of the light emitted by the laser is typically in the range of 400 to 700 nanometers.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.
What is the difference between a laser pointer and an infrared laser pointer?
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
What is the angular spread of the light emitted by a laser beam?
The angular spread of light emitted by a laser beam refers to the width of the beam as it diverges from its source. It is typically very narrow, with a small angular spread, allowing the light to travel in a focused direction.
What is the color of laser light?
Laser light comes in various colors depending on the type of laser being used. Common colors include red, green, blue, and violet. The color is determined by the specific wavelength of light being emitted by the laser.
Can a laser pointer make a rainbow with a prism?
A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.
What's the wavelength of the light emitted by the laser?
The wavelength of the light emitted by the laser is typically in the range of 400 to 700 nanometers.
What sends a narrow intense beam of light?
a small laser, or a laser pointer

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..
What is a laser modulator used for?
A laser modulator is used to change modulate a beam of light (or laser). The easiest way that they modulate the laser, or light beam, is by changing the rate at which the laser is emitted from the source.
Is it safe for cats to play with a laser pointer?
Yes, it is generally safe for cats to play with a laser pointer as long as precautions are taken to avoid shining the laser directly into their eyes. It is important to use the laser pointer responsibly and not let the cat become overly fixated on chasing the light.
How do you calculate the frequency of light emitted in chemicals?
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
What does the S in LASER stand for?
Stimulated Light Emitted by the Stimulated Emission of Radiation
Does any radio frequency used for laser communication?
no. LASER uses light frequencies.
What is the angular spread of the light emitted by a laser beam?
The angular spread of light emitted by a laser beam refers to the width of the beam as it diverges from its source. It is typically very narrow, with a small angular spread, allowing the light to travel in a focused direction.
