Types of Spectra: Continuous, Emission, and Absorption
WebA spectral line is like a fingerprint that can be used to identify the atoms, elements or molecules present in a star, galaxy or cloud of interstellar gas.If we separate the incoming light from a celestial source using a prism, we will often see a spectrum of colours crossed with discrete lines. Note that spectral lines can also occur in other regions of the … WebSep 8, 2024 · If the light that emerges is passed through a prism, it forms a continuous spectrum with black lines (corresponding to no light passing through the sample) at 656, 468, 434, and 410 nm. These wavelengths correspond to the n = 2 to n = 3, n = 2 to n = 4, n = 2 to n = 5, and n = 2 to n = 6 transitions. Any given element therefore has both a ... knowledge guru

A line spectrum is a series of lines that represent the different energy levels of the an atom. In this video, we'll use the Balmer-Rydberg equation to solve for photon energy for n=3 to 2 transition. ... The sun radiates like a so-called "black body" with temperature around 5700K. WebJan 10, 2024 · The frequency is shorter as it moves toward you, and the object shows a blueshift. If the object is moving away, it shows a redshift. This shows up in spectra of stellar light as a shift in the black lines (called absorption lines) as shown here).
