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.
Extreme poverty has long been defined as living on or below $1.25 a day, but the World Bankâs adjustment now sets the poverty line at $1.90 a day. The Bank said the change reflects new data on differences in the cost of living across countries, while preserving the real purchasing power of the previous yardstick.
