Accurate wavelengths of the ∼500 lines recorded are given in a table. This material is intended for wavelength calibration of near‐infrared spectra and is especially critical for high‐resolution work.

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

In recent years, there has been increasing demand from researchers and developers of MWIR lasers for an optical spectrum analyser that can quickly and precisely analyse the wavelength spectrum of ...

Yokogawa Test & Measurement's AQ6377E optical spectrum analyzer offers fast, precision mid-wave infrared (MWIR) measurements ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman Men Invented Very Unusual X-ray Guns. Each group contains a range of frequencies.

A black body not only emits radiation at a particular wavelength, but over the entire wavelength spectrum. The distribution of radiation over the spectrum depends entirely on temperature. The ...
