So for the sake of time you can skip it for the 1st attempt...Good luck aspirants 🙏🙏

[Abhi-..]

Instead of attending the big big lectures of modern physics I watched ur revision video directly and then did this question video believe that I am able to do each and every question very high sir🙏🙏🙇‍♂️🙇‍♂️🙏🙏

[Mynotes-mruw]

21:17 linear momentum conservation
24:01 work function based question
43:14 wavelength ka formula for electron and photon is different.
46:39 revisit
49:00
51:14 energy is directly proportional to mass
1:05:55 good question involving concept from magnetism
1:10:50 do it again
1:22:00 conservation of momentum but easy
1:33:00 good question
1:36:00 binding energy equation
1:45:47 do it again
2:20:12 direct formula based ques on number of spectral lines

Learnings only of two attempts
Sometimes energy can be equated in this way
mc^2 = hc/lambda
1Ci = 3.7 * 10^10 Bq
SI unit is Bq
Decay of proton to neutron only possible inside the nucleas
Energy of five levels in hydrogen should be remembered
n = 1 -13.6 ev
n = 2 -3.4 ev
n = 3 -1.5 ev
n = 4 -0.85ev
n = 5 -0.34ev

Lyman is UV
Balmer is Visible
Paschen Brackett Pfund are infra

Activity = Number of molecules * lambda
N = Nnot*e^-lambdat
A = Anot*e^-lambdat
lambda can be replaced by ln2/half life for easier calculations
Effective half life is just like parallel resisotors

R is directly proportional to n^2/z
v is directly proportional to z/n
E is directly proportional to z^2/n^2
E is also directly proportional to mass

It's 5:00 AM, December 14th....I am done with Modern Physics (Short Notes + PYQs). I am working hard for my dream percentile. Your channel is a medium for me to see it early from a distance sir, and that brings a smile on my face every single day I get something done. You are truly a gift to us sir✨. Thank you 🙏❤.
