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

To calculate wavelength in nanometers, use the formula: wavelength (nm) = (speed of light in a vacuum) / frequency. The speed of light in a vacuum is approximately 3.00 x 10^8 m/s. Remember to convert frequency to hertz if necessary (1 Hz = 1 s^-1).

Mercury emits ultraviolet (UV) light with distinct lines at 253.7 nm, 365 nm, and 405 nm. These lines are characteristic of mercury and are often used in mercury vapor lamps and fluorescent lighting.
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.
Both continuous bright line spectrum and spectral lines are related to the emission of light by atoms. A continuous bright line spectrum shows a broad range of colors without any gaps, while spectral lines are discrete lines representing specific wavelengths emitted by atoms. Both can be used to identify elements and study their atomic structure.
