Simple Derivation of the Exponential Decay Equation

By using the definition of activity, we will derive the radioactive decay equation. Then using this equation, we will find the relationship between half life and the decay constant.

This is the best I've seen. Easy to comprehend.

A quick, cool, comprehensive explanation. Thanks!

[heinhtetaung]

Thank you for helping with my puzzle. I have a different question and explanation here clears up my mind

[gladysmdinga]

thanks so much mum .I super love you. continue helping us🥰🥰🥰🥰🥰🥰

Very good video and clear explanation thank you very much . One suggestion is dont put background music in your videos or atleast make it quiter because its a little distracting .

[Chivende]

Beautiful explanation but since we're learning it's same as in class, the music is a bit distracting, it'll be better without it

The music is very distracting tho, I can't imagine trying to watch a lecture and having music playing in the background.

hi i am big fan of your video's vt.i wish you were my high school teacher . your contents are superb . providing contents for nothing . i think that my parents wasted money on school for tution fees . i will give you all my support vt . you are an absolute splended teacher . i think one of the main reason why your channel has very low acceleration is because people will not be able to get your videos when they search on YouTube . i think try adding more captions to your videos will help boost your channel

Why do you only add the constant of integration to one of the integrals?

Isn't it half life = ln half / lambda?
