Tried looking it up and it got complicated real quick.
In: Physics
T=t/n
T is the half life
t is the amount of time that has passed
n is the amount of half lives that have passed
If you take a chunk of pure radioactive material and let it decay for 1 year, then find that 25% of it is has decayed they you know that only half a half life has passed so…
T=1(year)÷.5(half life’s passed)
T=2 years
To calculate uranium you have to use incredibly small number, large samples, and way to count atoms. But it’s doable, and now you can change the equation to t=n•T to find out how old something is.
