The territory is slightly smaller than the combined area of Maryland and Delaware in the United States. Taiwan occupies a total area of 35,980 square kilometers (13,892 square miles). Its capital city, Taipei, is in the northeast, and is the most densely populated area in the territory.
continuous spectrum. n. (General Physics) a spectrum that contains or appears to contain all wavelengths but not spectrum lines over a wide portion of its range. The emission spectrum of incandescent solids is continuous; bremsstrahlung spectra consisting of a large number of lines may appear continuous.
Visible spectrum. The visible spectrum is a very small portion of the electromagnetic spectrum that can be seen by human eyes. This is shown in the figure below, which is not to scale. The exact boundaries of each type of wave are not precisely defined and often different authors have slightly different values.he limit between ionizing and non-ionizing radiations is located somewhere in the UV region, but it's not clearly defined and somehow fuzzy. A photon energy of 10 eV (corresponding to 124 nm) is often considered the threshold between ionizing and non-ionizing radiation, but there is no consensus on this topic.
