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 unit of frequency is the hertz. The period (T) of a wave is the time that it takes for one complete oscillation. The unit of period is the second. The period and frequency of a wave are linked by the following relationship, The speed (v) of a wave is the distance travelled per unit time by the wave.The unit of speed is the metre per second, m s -1.The speed, frequency and wavelength of a wave are linked by the following relationship,he period and frequency of a wave are linked by the following relationship, The speed (v) of a wave is the distance travelled per unit time by the wave. The unit of speed is the metre per second, m s -1.
