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.
List three factors that determine the height, length and period of a wave. Waves are generated by winds blowing across the surface of the water. The main factors that determine wave characteristics are the wind speed, the length of time that the wind blows, and the expanse of water (fetch) affected. The longer period waves arriving at a beach were generated in distant storms at sea. Shorter period, choppy waves move at slower speeds and are dissipated at sea through wave interference.
