Planck's constant using LED | Planck's Constant Experiment

This video demonstrates an #Experiment on measuring Planck's constant using LED. #PlancksConstantUsingLED
To determine the Plancks constant using LED, one needs to find out the knee voltage of the LED and to find out the knee voltage, one needs to draw the I-V characteristic of the given LED.
h*nu=eV
To determine the Planck’s Constant using different colours LED's.

This was very help full ..thank you

[@PhysicsLearningwithDrShaw]

Glad it helped

[@subratokumarmahato3959]

Can we get the whole vi characteristics for green and yellow as well please?

[@BKhadanga]

Sir please tell how to identify knee voltage from graph

[@naveenvaid4318]

led's symbols are wrong its 180degree changed in the kit

[@manjulatarana9180]

Thankyou 😊

[@Sam-wk9qg]

Plot it on graph as well ;)

[@sahilgopal8339]

Thanks sir 😊😊

Welcome

[@GigaChad-zx9hj]

How did you find out wavelength like of red it was 700. How did you get 700?

[@PhysicsLearningwithDrShaw]

Aim was to calculate the Planck's constant. So, Wavelength was provided not calculated.

[@GigaChad-zx9hj]

@@PhysicsLearningwithDrShaw Thanks Sir understood

[@Amitshakya563-z4n]

Having all colours own wavelength

[@djdragon9961]

Bhai insta id de sktai ho apni

[@nareshraut7522]

Iska calculation kaise nikalna hai

[@allrounderavi6994]

How you got knee voltage

[@manmohan_sharma_arts]

Ek hmaare professor h jo hme kuch smjhte nhi , kyunki hum bechaare open k student h isliye saala hme koi experiment krwaate hee nhi h

[@Praveenearningonline]

Graph kon batayega be 😅
