The weber fraction

WebNov 18, 2024 · The Weber fraction is the difference threshold divided by the standard duration tested. The fractions will be estimated in the 300-ms and 900-ms duration ranges (standard durations). It will provide a first direct comparison of the stability of the Weber fraction for these nine marker-type conditions. WebQuestion: 1. Solve the following Weber Fraction problems.
