I never had this much fun while watching a physics video, this man is seriously great

[@SahanaGnanapandithan]

It’s chem

[@Awai_quotes]

Einstein got lucky everyone else proving his equations😂

[@a.pal_yt2018]

In the end I thought Millikan was odd out of Nobel Prize!!!

[@PrinceSarraf0314]

Einstein was the luckiest man in history he was the man behind the mind.😊

[@rishavjain5087]

Millikan got Nobel for somethin he didn't believe in

[@kh22576]

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@NancyPandey-pt8uo]

😂 🤣🤣

🤣🤣🔥🔥

[@whysoserious1150]

Just amazed by your explanation!!!

[@tenzingnyideon1872]

This channel is a life saver

[@urvashiparmar3278]

My doubts were clear instantly! Thank you sooo muchhh!

[@adupokh4490]

physics seems very interesting

[@psedits9891]

This is chemistry 😂

[@jayashreej3142]

Awesome ..nice explanation. Thank you

[@happilyever-after5072]

You are just awesome! I was having goosebumps listening to Robert Millikans story😂

[@abhi9386]

Awesome explanation ☺

[@ShivangB]

Very advanced teaching. Nice 👍

How do you calculate Plank's constant from that graph

[@dustyyutes6972]

Find y intercept then multiply by electron charge and then divide this number by the threshold frequency.

[@aradhanabhola7549]

Calculate tan theta by y axis/x axis

[@samsuddinansari9133]

Thanks a lot

[@ayushijha9634]

What is the significance of slope being constant ?

[@kazukawasaki97]

you know, different elements have different positive charges, so the rate at which voltage needed to stop electron should have been different,but its also easy to understand why slope must remain constant: as all metals having different work functions,still must abide by energy conservation,so its only natural to understand why all graphs must be parallel,if not it would ne like I input alot of energy but require alot less voltage to stop or vice versa so both can be understood as valid but the latter is way more logical, the reason milikan ig considered this odd was due to personal bias, as in, just think about it yourself,when you come across such an equation at face value you would immediately consider different materials having different rates of change this congruency of rate of change in enery in linear graph is also the reason why Plank's constant is so detrimental, it shows all factors depending "on" energy like motion and frequency connect to one another some way or the other

[@Iroha_Isshiki]

This is what we really call *Wasted in some sense*

[@prachi9432]

Super amazing

[@iknowtospeak]

Einstein’s me and milikan’s my friends

[@vivekgupta3692]

without watching I am sure this video is amazing.....😀👍

[@nacharamrenuka9539]

Nice explanation

[@nacharamrenuka9539]

Thank you

[@anilsurjewala3606]

Love your video

[@ancientboi]

Einstein be like: thnx for proving i won noble prz

[@fouziyabegum1159]

People listen s u during lockdown makes weard

[@devaprasath7776]

Super explain

[@Isanu0]

Hyach 😅

[@rajat9311]

English seekh ke anpad ka jhaant

[@SaiAbitathaDUCIC]

Hindi channel mein jaa Hindi medium ki aulaad

[@MenamPatir4912]

Hindi ka channel bhi hain chadar mor waha pe jaake dekhna chahiye tha na... Isilye toh tum log jese jhant logo ke liye do channel hain

[@beatforbest6333]

Sorry but true Hindi me samaj aata he

[@rajdeep__]

nhi humko English me bhi Ata hai 🤗💀

[@Siya6471]

try physics wallah
