WebApr 8, 2024 · 10.3: Emission Spectra. The incandescent light bulbs that have been phasing out over the past decade or so contain a very thin wire filament that emits light when heated. The filament in these bulbs is typically made of tungsten, since it can be heated to high temperatures without melting. WebNaturally occurring tungsten ( 74 W) consists of five isotopes. Four are considered stable ( 182 W, 183 W, 184 W, and 186 W) and one is slightly radioactive, 180 W, with an extremely long half-life of 1.8 ± 0.2 exayears (10 18 years).
