An example of einsteinium chemical studies is the chemical consequences of radioactive decay. With the relatively short half-life of Es-253 (20.47 days) one can study the in-growth of daughter Bk-249 (half-life 330 days) and grand-daughter Cf-249 (half-life 351 years).
The wave period is the measure of time it takes for the weave cycle to complete. We usually measure the wave period in seconds and represent it with the letter T. Before we find the period of a wave, it helps to know frequency of the wave, that is the number of times the wave cycle repeats in a given time period.
The amplitude of a wave is a direct measure of its? Energy.The amplitude is the measure of the distance between the Crest of the wave ( the top) and the equilibrium of the wave ( the line that goes directly through the center oâ¦f the wave) and this distance does in fact represent the amount of energy in a wave.
