... The result is an electromagnetic wave – a wave of electric and magnetic fields. - Each field creates the other. - The fields are mutually perpendicular to each other. - The fields can move through a vacuum (empty space.) Maxwell was able to show (mathematically) that these e.m. waves moved at 3x10 8 ...

615-0185 (20-010) Instructions for Dip Needle
... To use the unit in dip needle form, position it such that the housing, which holds the needle and the scale, is perpendicular to the upright shaft. You will notice that the needle will deflect by a certain amount, which can be read on the scale. This deflection is known as inclination. Unfortunately ...

The value of λ is negligible for very light atoms, but increases with increasing atomic weight, so that for heavier d-block elements, and for f-block elements, the orbital contribution is considerable. For 2nd and 3rd row dblock elements, λ is an order of magnitude larger than for the first-row anal ...

Aurora
An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes. Different aspects of an aurora are elaborated in various sections below.
