to convert to nm you times your answer by 1e9 (1x10^9)
(6.626e-34) / (83)(6.7) = 1.19e-27 nm
Second calculate and you'll get an answer in m
(6.626e-34) / (6.00e24)(2.90e4) = 3.81e-54 nm
because the emission wavelengths of mercury are very precisely known.
In chemistry, nm typically stands for nanometers, which is a unit of measurement equal to one billionth of a meter. It is commonly used to measure the size of molecules, atoms, and wavelengths of light.
The hydrogen atom has four spectral lines because it undergoes transitions between its energy levels. These transitions produce four distinct wavelengths of light in the visible spectrum: 656.3 nm, 486.1 nm, 434.0 nm, and 410.2 nm. Each line corresponds to electrons moving between different energy levels in the atom.
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
In a continuous spectrum, you see every color in visible light from wavelengths around 380 nm to 780 nm. The bright light spectrum has only light at specific wavelengths, forming narrow regions of lights. This is characteristic of a particular substance, emitting these lights from its unique electron configuration. Light at specific wavelengths is emitted for different substances, but not a continuous rainbow.
375 to 750 nm
Infrared light has longer wavelengths compared to ultraviolet light. Infrared light wavelengths range from about 700 nm to 1 mm, while ultraviolet light wavelengths range from about 10 nm to 400 nm.
The colors of the rainbow and their corresponding wavelengths are: Red: 620-750 nm Orange: 590-620 nm Yellow: 570-590 nm Green: 495-570 nm Blue: 450-495 nm Indigo: 420-450 nm Violet: 380-420 nm
Wavelengths below 350 nm are absorbed by Earth's atmosphere, primarily by ozone, oxygen, and nitrogen. Wavelengths above 750 nm are absorbed by the eye's photoreceptors, causing them to be outside the visible spectrum.
Light in the visible spectrum ranges from 400 nm to 700 nm wavelengths. This includes light in the colors of violet, blue, green, yellow, orange, and red.
The measurement used for the wavelengths of color is typically in nanometers (nm). Each color has a specific range of wavelengths in the visible spectrum, with red having longer wavelengths around 700 nm and violet having shorter wavelengths around 400 nm.
The waves with wavelengths between about 400 mm and 10 nm are referred to as microwaves and ultraviolet rays, respectively. Microwaves have longer wavelengths, while ultraviolet rays have shorter wavelengths.
The common unit of identifying visual wavelengths is nanometers (nm). Visible light ranges from approximately 400 nm (violet) to 700 nm (red) on the electromagnetic spectrum.
Any whose wavelength does not exceed 379 nm.
The human eye can perceive light wavelengths ranging from approximately 380 nanometers (nm) to about 750 nm. This range encompasses the visible spectrum, which includes colors from violet (shorter wavelengths) to red (longer wavelengths). Beyond this range, ultraviolet light (below 380 nm) and infrared light (above 750 nm) are not visible to the human eye.
Infrared light has longer wavelengths compared to ultraviolet light. Infrared light ranges from about 700 nm to 1 mm, while ultraviolet light ranges from about 10 nm to 400 nm. Ultraviolet light has higher energy and shorter wavelengths than infrared light.
The first lines in the Balmer series of hydrogen correspond to transitions to the n=2 energy level. The wavelengths of these lines are 656.3 nm (Hα), 486.1 nm (Hβ), 434.0 nm (Hγ), and 410.2 nm (Hδ).
