Concept explainers
Interpretation:
The age of the carbon-14 present in the cloth has to be given.
Concept Introduction:
Radioactive Law:
The radioactive law states that the probability per unit time that a nucleus will decay is a constant independent of time. This constant is called the decay constant and is denoted by
Where N is the number of radioactive nuclei remaining after time t.
N0 is the number of radioactive nuclei in initial time.
k is the decay constant.
t is the time required to decay.
Half life period:
The half life is defined as the amount of time it takes for a given isotope to lose half of its radioactivity.
Where k is the decay constant.
