... using the principle of refraction—as stated by Snell's law—to disperse a light beam into its components. This happens because a ray of light is refracted (or bent) as it passes from air to glass, and this refraction is slightly different, depending upon the specific wavelength of light. One big disa ...

... The 23.5° angle between Earth’s spin axis and its orbit about the Sun gives rise to the seasonal cycle, causing the length of the day and the sunlight angle to vary during the year. As a result, summer is much warmer than winter, and polar regions are dramatically colder than the tropics. Also, Eart ...

... at a 3.5-σ level in the 0.3–8.0 keV band. Their positions, with an uncertainty of 0.00 5, their total photon counts and their counts in three separate energy bands (0.3–1.0 keV, 1.0–2.0 keV and 2.0–8.0 keV) are listed in Table A.1. The positions of the ROSAT sources given in Table 3 of Immler et al. ...

One of those problems wh ich bothered optical and UV astronomers during the past years is the discrepancy of the observed ratio of the Lya and H ...

The present experiment uses secondary muons corresponding to more energetic cosmic-ray protons that are still modulated by the ...
