***B*** ∻Key Concept∻ ⚹Emission Spectrum⚹ ∻Explanation∻ ⚹When mercury vapor is energized, it emits light at specific wavelengths. Viewing this light through a prism will show the emission spectrum, which consists of bright lines at these specific wavelengths.⚹◊What is the difference between a substance's absorption spectrum and emission spectrum in terms of their wavelengths?⍭ Generate me a similar question◊
