When an atom <strong>absorbs energy<\/strong>, an electron can become &#8220;excited,&#8221; meaning it moves from a <strong>lower energy level to a higher one<\/strong>. This is called <strong>absorption<\/strong>, and the energy absorbed corresponds to a specific wavelength of light that is <strong>removed from a continuous spectrum<\/strong>\u2014this is why absorption spectra appear as dark lines against a colored background.<\/p>\n\n\n\n<p>Conversely, when the excited electron <strong>falls back down to a lower energy level<\/strong>, it <strong>releases energy<\/strong> in the form of light at a specific wavelength. This emitted light forms the <strong>emission spectrum<\/strong>, which appears as bright lines against a dark background.<\/p>\n\n\n\n<p>The wavelengths that appear in an atom\u2019s <strong>emission spectrum<\/strong> correspond to the energy <strong>differences between two energy levels<\/strong>. Similarly, the <strong>absorption spectrum<\/strong> shows the <strong>same wavelengths<\/strong>, because they represent the exact amount of energy needed to excite an electron from a lower to a higher energy state.<\/p>\n\n\n\n<p>Therefore, the <strong>emission and absorption spectra of an atom consist of the same wavelengths<\/strong>, but they appear in opposite ways (bright lines for emission, dark lines for absorption).<\/p>\n\n\n\n<p>For example, in a hydrogen atom, visible emissions occur when electrons fall to the <strong>n=2 level<\/strong> from higher levels (Balmer series). These transitions emit visible light at specific wavelengths like <strong>656 nm (red), 486 nm (blue-green), 434 nm (violet), and 410 nm (violet)<\/strong>.<\/p>\n\n\n\n<p>In absorption, the atom absorbs photons of <strong>those exact wavelengths<\/strong> to raise electrons from the <strong>n=2 level to higher energy levels<\/strong> (n=3, n=4, etc.).<\/p>\n\n\n\n<p>Thus, <strong>the absorption spectrum is essentially the inverse of the emission spectrum<\/strong>, but both involve the <strong>same set of wavelengths<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What wavelength(s) appear(s) in the atom&#8217;s emission spectrum?
