Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string; for example, in a musical instrument like a guitar string. Depending on how the string is p
The Future of Poverty: Framing Uncertainty 75 Given both the weak basis for forecasting and slow change historically in domestic distributions, a fundamentally ï¬ at forecast is a reasonable pattern for the base case.8 Patterns of Potential Human Progress Volume 1: Reducing Global Poverty Third, however, those scenarios also remind us that the future is not simply a matter of different human action patterns.
1 Its gross monthly income â that is, its income before any of the programâs deductions are applied â generally must be at or below 130 percent of the poverty line. 2  For a family of three, the poverty line used to calculate SNAP benefits in federal fiscal year 2016 is $1,675 a month. Thus, 130 percent of the poverty line for a three-person family is $2,177 a month, or about $26,100 a year. 2  The poverty level is higher for bigger families and lower for smaller families. 3  Its net income, or income after deductions are applied, must be at or below the poverty line.
