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).
What is the wavelength of infrared?
The wavelength of infrared light ranges from about 0.7 micrometers to 1 millimeter.
What is wavelength nm?
Wavelength is the distance between repeating units of a propagating wave of a given frequency. For light waves, this value is often given in nanometers, abbreviated as "nm". A nanometer is 0.000000001 meters.
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
What does 925 NM mean?
925 NM likely refers to the wavelength of a light or electromagnetic wave, specifically in the near-infrared range. The "NM" stands for nanometers, which is a unit of length commonly used to describe the wavelength of light. In this case, 925 NM would indicate a wavelength of 925 nanometers.
What color is light with a wavelength of 470 NM?
Light with a wavelength of 470 nm is in the blue part of the spectrum.
What color has a wavelength of 530 nm?
A wavelength of 530 nm corresponds to green light.
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.
Calcium has a wavelength 649 nm and a frequency of 4.62e14 what is the color?
The color of light with a wavelength of 649 nm is red. This is because red light has wavelengths in the range of approximately 620-750 nm.
Which color of light has the shortest wavelength?
This is the violet color (380-450 nm).
What is the wavelength of a light wave?
The wavelength of a light wave is the distance between two consecutive points of the wave that are in phase, such as two peaks or two troughs. It is typically measured in units of nanometers (nm) or meters (m) and determines the color of the light.
What is the wavelength of the light produced by the lasers in CD drives?

What color has a wavelength of 540 nm?
A wavelength of 540 nm corresponds to the color green in the visible spectrum.
What wavelengths correspond to the visible spectrum Which color has the shortest wavelength The longes?
The visible spectrum ranges from approximately 380 nanometers (nm) to 750 nm in wavelength. Violet light has the shortest wavelength within this spectrum, around 380-450 nm, while red light has the longest wavelength, approximately 620-750 nm.
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.
What color light is being absorbed at 700 nm?
At 700 nm, red light is being absorbed. This wavelength corresponds to the red end of the visible light spectrum.
