Since that refractive index varies with wavelength, it follows that the angle that the light is refracted by will also vary with wavelength, causing an angular separation of the colors known as angular dispersion.

Since the 18th century, the unit has been used in low-precision measurements, for which small changes in Earth's gravity ( which varies from place to place by up to half a percent ) can safely be neglected .< ref > Acceleration due to gravity varies over the surface of the Earth, generally increasing from about 9. 78 m / s < sup > 2 </ sup > ( 32. 1 ft / s < sup > 2 </ sup >) at the equator to about 9. 83 m / s < sup > 2 </ sup > ( 32. 3 ft / s < sup > 2 </ sup >) at the poles .</ ref >

Since the upper atmosphere is not homogeneous and contains significant magnetic structure, the solar ultraviolet ( UV ), EUV and X-ray flux varies markedly in the course of the solar cycle.

Since the frequency of solar eruptive events is strongly modulated by the solar cycle, the degree of cosmic ray scattering in the outer solar system varies in step.

Since the angular speed of rotation of the galactic disk varies with distance from the centre of the galaxy ( via a standard solar system type of gravitational model ), a radial arm ( like a spoke ) would quickly become curved as the galaxy rotates.

Since the permanent magnet field is constant, the terminal voltage varies directly with the speed of the generator.

Since we are considering here relatively small diameter ( 1 - 1.5 inches ) fiber plates, their average thickness can be kept below 1/4 inch and their internal losses may be assumed as 15 percent ( per plate ).

Since that time, the rate of crater production on Earth has been considerably lower, but it is appreciable nonetheless ; Earth experiences from one to three impacts large enough to produce a 20 km diameter crater about once every million years on average.

Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangle was equivalent to the diameter of the tube's face.

Since beams typically do not have sharp edges, the diameter can be defined in many different ways.

Since the barrel is not circular in cross-section, it cannot be accurately described with a single diameter.

* Since the mass of the metal being imploded ( tamper plus pit ) is reduced, a smaller charge of high explosive is needed, reducing diameter even further.
