Sir, you do an amazing job. Your way of interpretation is simple, and too informative! I shared your nuclear physics playlist with my friends, and they do admire it. Keep the hard work up! Follow you from Egypt! 🌏
@@FortheLoveofPhysics I myself as a student of physics admire ur good work. Ur explanation is very simple and understandable. Keep it up. Love ❤ from Bhagalpur, Bihar.
Polite Request:- after completing the proof of any equation please get to the side of the screen so that we can take screenshot of the whole proof. Other then this you are doing fabulous work
Sir, thank you very much for your videos. your method of teaching is amazing...its difficult to find such a good teacher like you for this subject even in sri lanka also...knowledge and explanation skill are two things. Lot of teachers have a good knowledge, but they are fail in explaining something to others. I appriciate your work and it is very helpful to my studies. good luck...
A wonderful explanation from u that ur Interactiveness is quiet awesome and u makes the topics intesting and joy full thanks for that lesson... Lots of love from INDIA.... 💚💚
The way you teach the knowledge you share the way you explain are unique sir you clear my all doubts thanks you so much such a nice explanation .keep it up
How wish I can understand physics like him, but no giving up still on the process of achieving a milestone with the help some of his significant lecture.🍾🍾🍾🍾🍾🍾
Superb explanation..and very good content knowledge .I had a query that if an element is radioactive..then each and every atom should have disintegrated at same instant ..but going through this tutorial my doubts are clear Thank you
1. The half-life of a radioactive element is 4d. Determine the decay constant of the element. 2. The half-life of 238 U is 450 million years. Calculate the mean life and decay constant? 3. The half-life of radioactive is 30 days. Find the value a) break/decay constant b) mean life. 4. Average life of radium is 2294 years. Find its decay constant and half-life.
In the c-14 problem, why arent we convertion the disintegration per min into disintegration per sec. Is it okay to do the problem without any conversation according to the units mentioned for activity? M confusef
Great teaching Professor.. Appreciate your efforts to make things utterly simple to understand by analogical examples. I have few doubts, which I hope you will try to find time to clarify. How half lives of different isotopes are measured. Like, I can guess, for radio-isotopes with half lives in days, months or few years, it can be measured from the slope of their decay curves made from periodic measurements of chemically separated samples. But for isotopes having half lives in nanoseconds, microsecond or even seconds and minutes how it is measured? Also for isotopes like U-238 which has half lives in billions of years, which virtually does not decay at all in measurement time scales, how practically their half lives are measured? I hope and wish that, you will come up with a video for these doubts. Thank you so much
Half life is one parameter. If you take any radioactive material, and calculate its mass variation over a sufficient time period, you can plot it as an exponential function and from there derive all necessary parameters
@@FortheLoveofPhysics How practically it is possible to estimate half life of a short-lived radionuclide e.g. Po-214 or Po-218 or Po-212 and there are many others, whose half lives are in micro or nano seconds. In practical measurement time scale mass variation can not be measured, as in a second all activity will be decayed to near zero level.
May I suggest you do a video on the (alleged) randomness of radioactive particle decay? This actually can't be "RANDOM" since the half-life period is an exact CONSTANT for every element. If it would be TRULY random (i.e. not dependent of ANYTHING, including particle properties like the element's mass), any half-life time period would not EXIST at all. So aren't there hidden variables that exactly DETERMINE when that one particle HAS to decay? And if there aren't hidden variables, how can radioactive decay be deterministic?
Imagine you throw 60 dices together, then you can say with a degree of certainty that 10 out of those dices will display number "1". This is how probability works. Although you cannot predict which number will be displayed when u throw one dice, but when you repeat the experiment for many dices, you can give an estimate of probability. It is the same with radioactivity. You CANNOT predict when one radioactive nuclei will decay. But if u have 100 radioactive nuclei, then u can say with certainty how long will it take for 50 of those to decay. This is how half-life is defined. I did a video on Gamow's theory of alpha decay, which basically gives us a clue how quantum mechanical tunneling which is a probabilistic event leads to radioactive decay . If u are interested, you can check that out: ua-cam.com/video/suj5MTLGAUU/v-deo.html
Sir, I have one question considering 238 Uranium which has a half-life(T/2) = 4.5x10^9 yrs. The decay rate(dN(t)/dt = λN(t)) and λ-> decay constant. At t=0, dN(0)/dt = λN(0) obtained experimentally as decays per unit time(Bq or curie), at t=half-life=T/2, can you or any physicist prove experimentally that dN(T/2)/dt = λN(T/2) = 0.5dN(0)/dt ? If not, then half-life(T/2) = 4.5x10^9 yrs of 238U is just assumed based on a single derivative of a decay function.
Assalamualaikum sir .ur lecture so amazing but I have confuse in half life . Q.if some element have half life very small than why that element are still remains like polynium half life 3mint
Sir I have a question. If any radioactive element decay half of the original element, then that original element now will be other than it was , mean that it will now become some other nuclei , Sir in this Change in element will the decay constant LAMBDA be change???
