The Synthesis of "spectroscopy"

Discover spectroscopy, the science of analyzing light to reveal the chemical makeup of stars, planets, and galaxies. Learn why it's key to JWST's discoveries.

An explanation of absorption spectra and how these unique "fingerprints" of elements are used to analyze materials from distant stars to our own planet.

Discover the unique light "fingerprint" of elements. Learn how emission spectra help us identify the chemical makeup of stars, materials, and more.

Discover diffraction, the phenomenon where waves bend around obstacles. Learn how it affects everything from light to astronomical observations.

Discover the radial velocity method, a key technique using the Doppler effect to find distant exoplanets by observing tiny stellar 'wobbles'.

Explore the full range of light, from radio waves to gamma rays. Learn how the electromagnetic spectrum shapes our technology and view of the cosmos.

An introduction to physical chemistry, the branch of science that uses physics to understand chemical systems, driving innovation in tech and medicine.

An introduction to infrared, the invisible electromagnetic radiation we feel as heat, and its growing applications in technology, health, and more.

Discover what wavelength is and how this fundamental property of waves shapes everything from the colors we see to the technology we use daily.

Discover what gamma rays are, why they're a hot topic in science and medicine, and how this powerful radiation affects human health.
