hey everyone, do you know the formula used to compute for the AGE of a substance if its half-life and fraction remaining are given? please help me.. thank you..
The formula for calculating age using half-life and fraction remaining is: Age = ln(Fraction Remaining) / (-0.693) x Half-Life
Half-life is the amount of time it takes for half of a radioactive substance to decay. It is used in the calculation of age because it allows us to estimate how much of the substance has decayed and how much is left.
Yes, this method can be used for any radioactive substance as long as the half-life of the substance is known. The formula remains the same regardless of the substance.
The natural logarithm (ln) is used because it is the inverse function of exponential decay, which is the process by which radioactive substances decay. This allows us to calculate the fraction remaining, which is needed in the formula for calculating age.
This method provides an estimate of the age of an object based on the amount of a radioactive substance present. It is not always accurate for determining the exact age, but it can provide a good estimation within a certain margin of error.
