Webamplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other. Waves are generated by … WebMay 9, 2024 · Half-life. As defined by geophysicists, the half-life (or half-value period) of a substance is the time required for one-half of the atoms in any size sample to radioactively decay. Radioactive elements have different isotopes that decay at different rates. As a result, half-life varies with regard to the particular isotope under consideration.
WebAnd this is the idea of half-life. Let's look at the definition for half-life here. It's the time it takes for 1/2 of your radioactive nuclei to decay. So, if we start with four milligrams, and we lose 1/2 of that, right, then we're left with two milligrams. And it took 14.3 days for this to happen. So 14.3 days is the half-life of phosphorus-32.
