Examples of incandescence in the following topics:
-
- Fluorescent lights are about four times more efficient than incandescent lights—this is true for both the long tubes and the compact fluorescent lights (CFL).
- Thus, a 60-W incandescent bulb can be replaced by a 15-W CFL, which has the same brightness and color.
- CFLs have a bent tube inside a globe or a spiral-shaped tube, all connected to a standard screw-in base that fits standard incandescent light sockets.
- CFLs are much more efficient than incandescent bulbs and so consume much less energy for the intensity light produces.
-
- Figure 12.5 shows shocked air heated to incandescence about two milliseconds after the detonation of a nuclear bomb.
-
- A material is heated to incandescence and it emits a light that is characteristic of its atomic makeup.
-
- Visible light or ultraviolet-emitting lasers can char paper and incandescently hot objects emit visible radiation.
- Objects at room temperature will emit radiation mostly concentrated in the 8 to 25 µm band, but this is not distinct from the emission of visible light by incandescent objects and ultraviolet by even hotter objects (see sections on black body radiation and Wien's displacement law).
-
- For example, a 60-W incandescent bulb converts only 5 W of electrical power to light, with 55 W dissipating into thermal energy.

- The figure from the "Problems" section of chapter 12 shows shocked air heated to incandescence about two milliseconds after the detonation of a nuclear bomb.
