The spectrum in a rainbow. A spectrum (pl.: spectra or spectrums) [1] is a condition that is not limited to a specific set of values but can vary, without gaps, across a continuum. The word spectrum was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.
Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. It is a fundamental of taxonomy that nature rarely deals with discrete categories... The living world is a continuum in each and every one of its aspects. While emphasizing the continuity of the gradations between ...
Although the solar corona is a source of extreme ultraviolet and X-ray radiation, these rays make up only a very small amount of the power output of the Sun (see spectrum at right). The spectrum of nearly all solar electromagnetic radiation striking the Earth's atmosphere spans a range of 100 nm to about 1 mm (1,000,000 nm).
The Spectrum (French: Le Spectrum de Montréal) was a concert hall, in Montreal, Quebec, Canada, that closed on August 5, 2007. Opened on October 17, 1952, as the Alouette Theatre , it was briefly renamed Club Montreal before receiving its popular name.
The polarizability ellipsoid of spherical top molecules is in fact spherical so those molecules show no rotational Raman spectrum. For all other molecules both Stokes and anti-Stokes lines [ notes 5 ] can be observed and they have similar intensities due to the fact that many rotational states are thermally populated.
This questionnaire is typically used to screen toddlers up to 2.5 years old, but it may still be helpful for children up to 4 years old. It doesn’t offer a diagnosis, but it may give you an idea ...
Solar spectrum with Fraunhofer lines as it appears visually. In 1802, English chemist William Hyde Wollaston [2] was the first person to note the appearance of a number of dark features in the solar spectrum. [3] In 1814, Joseph von Fraunhofer independently rediscovered the lines and began to systematically study and measure their wavelengths ...
The bipolar spectrum is a term used to refer to conditions that include not only bipolar disorder as traditionally defined (that is, clear episodes of mania or hypomania as well as depressive ...
