Observing Stars.

Observing Stars Our view of the sky at night is doable because of the waiver and reflection of light up. Light is the better-known term for the electrocharismatic spectrum, which includes waves in the seeable, ultra-violet, infra-red, microwave, radio, roentgenogram and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several(prenominal) overlap each other. Each of these regions in the electro magnetised spectrum incorporate transverse waves, travelling as electrical and magnetic palm which interact perpendicularly to each other, with different ranges of wavelength. The magnetic issue oscillates vertically and the electric stadium horizontally, and each field induces the other. By the end of the nineteenth century, Maxwell gave a hardheaded apprize for c, the speed of light: c = __1__ = 3 x 108 ms-1 Ö(mo eo) The alliance between the speed of all electromagnetic radiation, wavelength (l) and absolute frequency (f) is shown to be c = l f . Because the Universe is so vast, interstellar exceeds ar so great that light emitted can throw up of millions of old age to reach us. Such large distances are very frequently measured in light-years; one light-year (ly) is the distance travelled by a wave of light in a year. Because of the broad speed of light and distances, the light arriving at us would crap left the object many years ago, so that sounding at a far apart star is much resembling looking back in time.

scientific observation of the stars is difficult because of the distorting moment of the Earths atmosphere. One problem is atmospheric refraction-where light is bent. Turbulent ai! r currents cause varying deflective indices, as there is no uniform air density. This causes an effect called scintillation, where stars seem to twinkle. The effect on regions of the electromagnetic spectrum other than the visible part, such... This sounds like its taken straight from a book. You have no paragraphs to put in up this information.
