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 is laser light different from light emitted from a flashlight?
Laser light is different in many ways. These are the biggies. a) Laser light is almost monochromatic. Because it is created by exciting a specific substance to emit photons, the light emitted by the source is almost all one specific wavelength. The light from a flashlight contains all of the colors in the spectrum, forming "white light". b) Laser light is very coherent. This means that the waves leaving the laser remain in phase for a very long time. Light from a flashlight is not coherent. As a result, a laser can project a distinct beam of light much farther than a flashlight. c) Laser light is directional. This means that the beam of light being emitted does not spread much with distance. Hence it can still appear as a point of light many meters away from the source. A flashlight beam will quickly spread the further it is viewed from the source. Because of these fundamental properties, lasers are an excellent experimental device.
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.
What is the color of a laser light?
The color of a laser light depends on the wavelength of the light being emitted. Common laser colors include red, green, blue, and violet, with each color corresponding to a specific wavelength range.
What light is only one color?
Monochromic light can be photons in a narrow energy range emitted by a laser. Sunlight looks uniform but it is actually composed of all of the wavelengths of visible light (except for a few that have been absorbed in the atmosphere).
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 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.
What does the S in LASER stand for?

What is measured in the unit candelas?
candela measures the amount of light emitted in the range of a (three- dimensional) angular span.

What tool is used to help determine the colors of light emitted by a flashlight?
A spectrophotometer is typically used to determine the colors of light emitted by a flashlight. This device can measure the spectrum of light emitted and provide information about the specific colors present.
What is the frequency of light emitted by a laser pointer whose wave is 670 nm?
The frequency of light emitted by a laser pointer with a wavelength of 670 nm can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values, we get frequency = 3x10^8 m/s / (670x10^-9 m) = 4.48x10^14 Hz.
What is light source that has only one wavelength of light and will not spread out when passed through a prism is defined as?
A laser is a light source that has only one wavelength of light and will not spread out when passed through a prism. The light produced by a laser is coherent, meaning all the photons are in phase with one another.
