Astronomy - Essay Example 1 D. Advanced Computer methodologies are there which embed the light into arbitrary colors that are perceptible. The Hubble Space Telescope is intelligent to determine wavelengths starting from 0.1150 to 2 micrometers other than visible region. 2 A. Ions are charged particles whereas atoms are neutral. When an atom looses or gains an electron it is said to be ion. For example sodium metal in neutral state is composed of atoms where as sodium in sodium chloride is ion. 2 C. Hot objects release more of their light at short wavelengths. This is because of the reason that hot bodies have blue intensity peaks and thus the wavelength for blue color is relatively smaller whilst the cooler objects have red intensity peaks means their wavelength is relatively longer due to the color of the peak. 2 D. The spectrum produced from white light comprises of all colors is termed as a continuous spectrum. Continuous spectra are formed by all radiant solids, liquids and gases under high pressure. A gas at low pressure does not make a continuous spectrum but forms a line spectrum explicated as individual lines at definite frequencies of the gas. If the gas is manipulated luminescent by warmth or an electric discharge, the consequential spectrum is a bright-line, or emission, spectrum, consisting of a series of bright lines against a dark background. A dark-line, or absorption spectrum is the reciprocal of a bright-line spectrum; it is formed when white light comprising all frequencies transcends through a gas not hot sufficient to be radiant. 3. In astronomy, spectral classification is a classification of stars founded on their spectral distinctiveness. The spectral classification arrived at a specified class of a star explicating the radicalization of its chromospheres, what atomic excitations are mainly well-known in the light, providing a purposeful determination of the temperature in chromospheres. Light from a specific star is assessed by breaking it up
