In our question we are given that carbon 14 dating is used to date a bone found at an archaeological excavation.
00:06
Now the ratio of c14 to c12 is given to us with the following value, we need to determine how old is the bone.
00:13
Now here the atom c14 is a radioactive element.
00:21
That is, it has a half -life.
00:27
Now we are given the ratio of c -14 to c -12 atom in living organism which is generally 1 .3 into 10 to the power minus 12.
00:39
Now when the living organism is dead, then the concentration of c12 remains same but the concentration of c14 decreases.
00:51
As a result, the ratio of the amount of the c14 to c12 also decreases.
00:57
Now the half life of c14 is 5730 years.
01:03
It is required to find the ratio of c14 to c12 in the sample to the ratio of c14 to c12 in living organism.
01:12
This will be done in order to find the age of the bone...
