What is the wavelength of the light produced by the lasers in CD drives?
Originally, CD lasers with a wavelength of 780 nm were used, in the infrared.For DVDs, the wavelength was reduced to 650 nm (red color), and the wavelengthfor Blu-ray Disc was reduced to 405 nm (violet color).
Does a UV wavelength of 395-410 nm work as an black light?
Yes, a "black light" is an ultraviolet light with wavelength of about 395-410 nm.
What does nm in calculation of ultraviolet rays mean?
nm = nanometers It is a measure of the wavelength of the light, with energy inversely proportional to the wavelength: E = h / wavelength
What color is the wavelength of light in the balmer series that results from the transition of an electron from n4 to n2?
The n4-n2 transition of hydrogen is in the cyan, with wavelength of 486.1 nm. blue = als
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..
In what wavelength region does caffeine fluoresce?
When excited by 532 nm green light, caffeine has been seen to fluoresce in the 625 nm wavelength region. This is visible orange light.
What is the wavelength of a light wave?
If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.
Determine the energy of a single photon in a monochromatic beam of light of wavelength 625 nm?
1.99 eV
Which color of light has the shortest wavelength?
This is the violet color (380-450 nm).
What is the wavelength of the light produced by the lasers in CD drives?
Originally, CD lasers with a wavelength of 780 nm were used, in the infrared.For DVDs, the wavelength was reduced to 650 nm (red color), and the wavelengthfor Blu-ray Disc was reduced to 405 nm (violet color).
How does light become coloured?
Light's color depends on its wavelength. Shorter wavelengths make light more red, while longer make it more violet colored. Red light has a wavelength of approximately 700 nm, while violet light has a wavelength of 400 nm.
What is the wavelength of light waves?
If you mean visible light, that is between about 380 and 780 nm, depending on the color of the light. nm means nanometer - 1 nm = 0.000 000 001 meter. In other words, the wavelength of visible light is slighty less than a micron.
How small is wavelength of visible light?
Approximately in the range of 350-700 nm, depending on the color.
What two properties of light waves determine the color of the light?
Just ONE property, the wavelength of the light. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.
Can be from the frequency of a light wave?
The wavelength of visible light is approximately between 400 and 700 nm; if you divide the speed of light by that value, you will get the corresponding frequencies.
Wave length of red light?
The color of the wavelength lambda = 685 nanometers is "deep red". The wavelength lambda = 685 nanometers equals the frequency f = 503,852,870,588,235 Hz. 1 nanometer = 1×10−9 meter. 685 nm = 0.000000685 meters. Scroll down to related links and look at "Radio and light waves in a vacuum".
Does a UV wavelength of 395-410 nm work as an black light?
Yes, a "black light" is an ultraviolet light with wavelength of about 395-410 nm.
