001-ALEVEL PHYSICS PAPER 1 | RADIOACTIVITY (MODERN PHYSICS) | FOR SENIOR 5 & 6

In this video I take you the calculations on radioactivity in modern physics.
This involves calculations of half-life, activity, number of atoms in a radioactive sample, unified mass, einsten’s relation of mass and energy.
The video contains numerous worked examples from UNEB Question Bank; and is suitable to A-level students in Senior Five and Six offering Physics as part of their combination. E.g. (PCB, PCM, PEM, PMT, PMA, e.t.c)
