No bro your answer is incomplete. You didn't convert the energy into electron volt, for that you've to divide the given value by charge of electron because the answer you've written is E=hc/lamba= 6.02 and if you'll divide it by charge of electron then the answer will be 3.76 eV. So, Na and K will show photoelectric emission.
@adityasingh8632 2 hr ki jo sir ne krayi h wo complete kro fir ncert solution krlo dekh kr only fir pdho tb smjh aayega Mera to 1.5 din lg gya only ishi chapter me😪😪😪
1:42:42 Sir Thank you so so much for this pyq series ... My numerical portion is so good now and I'm not scared anymore ... Tomorrow is my phy paper and i watched all ur pyq videos ... It helped me a lottt .. thank you sir ✨
16:08 kinetic energy of e- emitted from metal A will be more, because the threshold frequency of metal A is more than metal B and frequency is directly proportional to energy.
Be chaman , threshold frequency directly proportional nahi hoti maximum kinetic energy ke balki frequency of incident radiation directly proportional hoti hai maximum kinetic energy ke . Aur incident radiation ki frequency same hai dono case me "v" . Metal A ki threshold frequency hai v/2 matlab kinetic energy me badalne ke liye sirf v/2 energy bachi hai . Lekin metal B ki threshold frequency v/3 hai aur ab 2v/3 energy bachi kinetic energy me badalne ke liye . Aur agar class 3 ki maths padhi hai to ye pata hoga ki 2v/3 > v/2 . So metal B ki maximum kinetic energy jyada hogi .
Sir app aise hi session late Rahiye thanks you sir Sir aapke hi wjh se meri physics strong ho paa rhi hai mene abhi to koii questions bank nhi liya bs aap jo pyqs krwaye ho me bs bhi krta hoo Thanks 🙏🙏🙏 sir for your efforts 🙂

1:03:20 is 4.24 x 10^-19
In J
Remember guys to put units as well otherwise you will lose half Marks 😊
Sir at 57:50 the answer for (a) will be 2ev as the unit specified for the question was eV
Correct vhai...1240ev/wavelength in nm aaraam se nikal jaayega utna calculation ka jrurat nai
