The James Webb Space Telescope's Spectroscopy - Another Update From NASA!

"The James Webb Space Telescope launched on 25th December 2021, will be responsible for spearheading humanity’s quest in understanding the mysteries of the universe and the cosmos. From looking for first galaxies, to hunting for distant exoplanets and planetary systems, the Webb Telescope can peer back into time to understand the history of our universe."

This is an information update from NASA as uploaded to YouTube by the YouCurious Channel and deals with a component within the JWST which handles Spectroscopy!

Okay, so Spectroscopy is defined as follows:
"Spectroscopy, is the study of the absorption and emission of light and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation. More recently, the definition has been expanded to include the study of the interactions between particles such as electrons, protons, and ions, as well as their interaction with other particles as a function of their collision energy." This is the beginning of the definition, but it really is more detailed than this short delineation... - Britannica

Further, "Spectroscopic techniques are extremely sensitive. Single atoms and even different isotopes of the same atom can be detected among 1020 or more atoms of a different species. (Isotopes are all atoms of an element that have unequal mass but the same atomic number. Isotopes of the same element are virtually identical chemically.) Trace amounts of pollutants or contaminants are often detected most effectively by spectroscopic techniques. Certain types of microwave, optical, and gamma-ray spectroscopy are capable of measuring infinitesimal frequency shifts in narrow spectroscopic lines. Frequency shifts as small as one part in 1015 of the frequency being measured can be observed with ultrahigh resolution laser techniques. Because of this sensitivity, the most accurate physical measurements have been frequency measurements." - Britannica

In the James Web Space Telescope, the Spectroscopy equipment fundamentally measures the elements contained in a wavelength of light... Watch and listen as the Narrator takes you through the basics of what the JWST will do for our Physics understanding of the early Universe!

I hope you enjoy it!
