Students, in this question a fossilized tree is curled by volcano was studied.
00:08
It has 10 .5 percentage of carbon 14.
00:15
Carbon 14 is equal to 10 .5 percentage found in the sample of the same size from a tree that is alive today.
00:24
So, when we have to calculate when did the volcanic eruption take place.
00:31
So, to calculate when did the volcanic eruption takes place, let us consider the amount of carbon c 14.
00:47
C 14 at given time be n t.
00:59
So, this n t can be given as n naught into e to the power minus lambda into t.
01:07
So, half life we know that the half life of carbon 14 is equal to 5700 years approximately.
01:21
Therefore, t half is equal to 5700 years.
01:31
So, lambda is equal to we have to calculate lambda...
