It was very informative, but at one point of time the demonstrator said She’ll be using a high frequency light and for that she is increasing the intensity of light. This is incorrect. Increasing the intensity of light does not increase the light frequency (intensity has nothing to do with frequency). Increasing the intensity of light means, she is increasing the number of photons to interact with the oncoming electrons (particles), which thereby increases the chances of collisions during the experiment. Colour of light depends on its wavelength [and hence on its frequency, c=nu x lambda)]. Using different filters provide access to different wavelengths of light used and hence its frequency could be selectively used.

I have a doubt,
In NCERT book it is given that intially first we let current to be saturated by providing positive p.d then we gradually increase p.d negatively, and the voltage measured when current become zero is our stopping potential.
But why in the beginning here we have not let the current to be saturated ?

Well explained shivani 😊

The most important thing is to cover the separation between photo sensor and lamp of photo cell by a Black body , so that there will be not any radiation in the form of heat 🙃

4:18 pe jo background mai bol rah hai same mai screen ke piche se bolne ki koshish kar rah tha

[@atlasiaSarthak]

Relatable 😂😅

[@anupkumaranupkumar8289]

Good didi aapne accha bataya...👍

[@aparnabiswas8312]

Ha 4:18 . Light ko screen kar k current zero karna sa kiya hota hai?

Well explained.. Thanks

[@sabeehashraf3793]

Your hand creating hurdle between source and photocell/filter...
Follow precautions properly

[@AutonomousAcademy]

definitely sir

Nice job

[@Kanwat73]

Very very helpful.

[@SajjadAhmad-g3l]

For high frequency we used different colors not used high intensity

[@tejaugaming1905]

Good explanation 🎉🎉🎉🎉❤❤❤
