What is Radioactive Decay? Half Life | Decay Constant | Activity (+ Problems Solving)

The Law of Radioactive Decay tells us how the number of a radioactive sample changes with time. Usually it is an exponential decay process. Even though the different radioactive processes like alpha decay, beta decay or gamma decay are different from each other in terms of the particles emitted etc, they all share the same kind of decay law. Half Life is defined as the time period in which the initial number of radioactive samples reaches half its original value. Decay constant and half life are inversely proportional to each other. These quantities are a characteristic of the radioactive sample present, and is independent of the physical parameters like pressure, temperature, density etc. Mean life is the average lifespan of all radioactive samples present. Activity is the rate of radioactive decay, or the number of disintegrations happening per unit time. Activity also decreases exponentially with time. We can use the conclusions derived from the decay law and other parameters to solve different problems of radioactive decay. ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ Support💖  / dibyajyotidas   Donate🤝🏻https://paypal.me/FortheLoveofPhysics Telegram - https://t.me/FortheLoveofPhysicsYT ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ Follow my other videos here... •••••••••••••••••••••••••••••••••••••••••• NUCLEAR AND PARTICLE PHYSICS - Series : •••••••••••••••••••••••••••••••••••••••••• 1) What is Nuclear Physics? ►    • What is Nuclear Physics? (LECTURE SER...   2) Nuclear Size / Radius ►    • Nuclear Size / Radius   3) Quantization of Angular Momentum ►    • What is Quantization of Angular Momen...   4) Nuclear Spin and Angular Momentum ►    • Nuclear Spin and Angular Momentum   5) Nuclear Magnetic Moment ►    • Nuclear Magnetic Moment   6) Binding Energy of Nucleus & BE Curve ►    • What is Nuclear Binding Energy? (and ...   7) Parity of Wave function ►    • What is Parity of a Wave function? (O...   8) Symmetric & Anti symmetric Wave func ►    • Symmetric and Anti-symmetric Wave fun...   9) Liquid Drop Model of Nucleus ►    • Liquid Drop Model of Nucleus ( Bindin...   10) Corrections to Liquid Drop Model ►    • Corrections to Liquid Drop Model / Se...   11) NZ Graph (& Maximizing BE) ►    • What is NZ Graph? | Maximizing Bindin...   12) Fermi Energy of Nucleus ►    • Fermi Energy of Nucleus (Derivation)   13) Fermi Gas Model of Nucleus ►    • Fermi Gas Model of Nucleus   14) Shell Model of Nucleus ►    • Shell Model of Nucleus   15) Nature of (Strong) Nuclear Force) ►    • Nature of (Strong) Nuclear Force   16) Alpha, Beta & Gamma Decay ►    • Alpha, Beta & Gamma Decay [Complete D...   17) Gamow's Theory of Alpha Decay ►    • Gamow's Theory of Alpha Decay AND Gei...   18) Gamow's Theory (DERIVATION) ►    • [DERIVATION ] Gamow's Theory of Alpha...   19) Q Value and KE of Alpha Decay ►    • Q-Value | KE of Alpha Decay (Kinematics)   20) Beta Decay & Neutrino Hypothesis ►    • Beta Decay & Neutrino Hypothesis !! (...   21) Radioactive Decay Law ►    • What is Radioactive Decay? Half Life ...   22) Nuclear Cross Section ►    • Nuclear Cross Section !!   23) Interaction of Nuclear Radiation with Matter ►    • Interaction of Nuclear Radiation with...   24) What is Cherenkov Radiaton? ►    • The Physics of Cherenkov Radiation   25) Nuclear Detectors ►    • Nuclear Detectors - Ionization Chambe...   26) Geiger Muller Counter ►    • What is a GM Counter? - Geiger Muller...   27) Scintillation Detector ►    • What is a Scintillation Detector?   28) Semiconductor Detectors ►    • What are Semiconductor Detectors?   29) What are Accelerators? ►    • What are Accelerators? + Electrostati...   30) Van de Graaff Generator ►    • Van de Graaff | Tandem & Pelletron Pa...   31) Linear Accelerator ►    • Linear Particle Accelerator (Principl...   32) Cyclotron ►    • Cyclotron (Principle, Construction, W...   33) Synchrotron ►    • Cyclotron & Synchrotron (Particle Acc...   34) Betatron ►    • Cyclotron & Synchrotron (Particle Acc...   35) Fission & Fusion ►    • Nuclear Fission and Fusion | What rol...   36) Proton-Proton & CNO Cycle ►    • Proton Proton Cycle & CNO Cycle   37) Meson Theory of Nuclear Forces ►    • Meson Theory of Nuclear Forces & Esti...   ••••••••••••••••••••••••••••••••••••••••••• NUCLEAR PHYSICS - PLAYLIST    • Nuclear Physics   ••••••••••••••••••••••••••••••••••••••••••• #NuclearPhysics
