What else can I help you with?
Light of a single wavelength and having all waves in phase is?
called coherent light. This light can produce interference patterns and is commonly produced by lasers due to its focused and efficient properties.
What radiation is used in a laser?
Laser radiation is typically produced using optical amplification of light, often from a stimulated emission process in a gain medium such as a solid, liquid, or gas. This produces coherent light of a specific wavelength which gives lasers their unique properties.
What color sensation is produced by light with a wave length of 5200 A?
Light with a wavelength of 5200 A produces a green color sensation.
What is the wavelength of sunlight?
Sunlight, which for the moment we'll consider to be visible white-colored light, is actually made up of many, many different wavelengths (colors) of light. Yes, a wavelength of light corresponds to its color, and a mixture of all the visible colors of light produces white light.How do we know? The fact that white light is actually a mixture of colors (and therefore, wavelengths) is demonstrated when we pass white light through a prism. The prism splits the white light into the component colors, which shine in separate bands of color as the light exits the prism.Blue light is a shorter wavelength, green and yellow are medium wavelengths, and red light is a longer wavelength. Ultraviolet, which is invisible, is very short wavelength light, while infrared, also invisible, is very long wavelength light. Sunlight contains these invisible lights as well as the visible colored lights.Answer:The color and wavelength of light that is produced is determined by what element produces it. The sun produces a lot of the group 18 (noble gases) elements so if you want to find the wavelength of sunlight you would have to measure the wavelengths of some of the Noble gases, UV radiation, and other forms of electromagnatic radiation.***************Actually, the second answer given is only partially correct. Light can be produced in a few different ways. If light is produced by changes in electron orbitals within an element (photoelectric effect), as happens in fluorescent lights, LEDs, lasers, or gas lamps etc., then indeed the wavelength of light is determined by the element and is thus restricted to a few discreet values.However, light can also be produced by 'blackbody radiation'. This is associated with hot objects - incandescent light bulbs, metal glowing when hot, even the infrared light emitted by human bodies. When light is produced in this way, it emits a continuous spectrum, meaning that many different wavelengths are produced, not just a few. The peak (strongest) wavelength will be determined by temperature alone, from an equation called 'Wien's law'.Both kinds of light are generated by the sun, but the blackbody radiation is much more powerful due to the high temperature of the sun. The surface of the sun is approximately 6000 degrees Kelvin, which means that the peak wavelength emitted by the sun is about 483 nm.This wavelength is in the middle of the visible range of colors. A coincidence? Not at all! Our eyes have evolved to be most sensitive to the colors that are most generated by the sun.For more information, see the related links below.
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
Light of a single wavelength and having all waves in phase is?
called coherent light. This light can produce interference patterns and is commonly produced by lasers due to its focused and efficient properties.
Do lasers olways give off light that is always red?
no, it depends on the wavelength
What light is produced by lasers?
Lasers produce coherent light, which means the waves are aligned and have a consistent phase. This produces a concentrated, intense beam of light with very little divergence.
What produces a intense light of a single color?
An intense light of a single color can be produced by a laser. Lasers are devices that emit light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. This results in a highly focused beam of light with a specific wavelength and color.
What radiation is used in a laser?
Laser radiation is typically produced using optical amplification of light, often from a stimulated emission process in a gain medium such as a solid, liquid, or gas. This produces coherent light of a specific wavelength which gives lasers their unique properties.
How lasers and ordinary light different?
Lasers produce coherent and focused light of a single wavelength, while ordinary light sources emit incoherent light of various wavelengths. Lasers also have a much higher intensity and can be tightly focused over long distances compared to ordinary light sources. Additionally, lasers have a very narrow beam divergence, whereas ordinary light sources have a broader dispersion.
What is a coherent light?
Coherent light is light where all the electromagnetic waves oscillate in phase with one another. This results in a uniform, well-defined wavefront that enables interference patterns to be produced, such as those seen in lasers. Coherent light sources are characterized by their ability to produce a narrow beam with a consistent wavelength and direction.
Does lasers alter the behavior of light?
Lasers do not alter the behavior of light itself, but rather produce a highly focused and coherent beam of light with specific properties such as directionality, intensity, and wavelength. The laser light maintains its inherent properties while being emitted in a concentrated and uniform way.
How do laser range finders use lasers?
Distance is measured based on the Doppler effect. This has to do with a phase change in the the light based on its wavelength
Can lasers go through water?
Yes, lasers can pass through water, but their effectiveness and ability to penetrate depend on factors such as the laser's wavelength and the water's clarity. In general, visible light lasers have limited penetration in water due to absorption and scattering effects, while infrared lasers can penetrate deeper.
What are some properties of light given off by lasers?
Some properties of light emitted by lasers include coherence (waves are in phase), directionality (highly focused beam), monochromaticity (single wavelength), and high intensity. These properties make lasers useful in a wide range of applications such as cutting, welding, communication, and medical procedures.
Why are lasers different from other kinds of light?
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.
