Dear PG team, Please add chapters to your revision checklist videos so that we can skip to the slide we want and I think it helps in SEO also. Thank you for the great lectures. I am currently using them for third attempt!

Case diary Dear authority, Name Parents name: Application number: I request you to postpone the Jee and Neet exams in light of the covid-19 pandemic. It is common knowledge that that conditions are not feasible for conducting such big exams. I request you to schedule the exams once we have crossed the peak of the pandemic and we are ready to bear any delay. I shall outline why it should be done with accurate arguments. 1) We have prepared SOPs with recommendations from experts in the field and have ratified it with the ministry. We know that this is an airborne virus. Mask dont help; ministers and officials who follow strict protocol have fallen victim. More so the SOP may be followed at the exam centre but would be useless during travel from home to the centre and back. Even a few students contracting the virus and then spreading it to others who might die or suffer from permanent lung damage. 2) The exams have already been postponed twice earlier and hence we haven’t been insensitive to the student fraternities demand. But the peak has yet not come and unless that happens our demands have not been met and the actions taken till now will be deemed hollow. 3) We are trying to ensure smooth transition of the academic year. But at what cost? Someone’s health is any day more important than the academic year. This is something that has affected the whole globe, we can very well afford to take a step back and consider extreme relaxation for extreme situations. This is a rare phenomena, and taking exams during this time is a punishment. 4) Admit Cards will be used as a pass to traverse through restricted areas. But for what? Travelling is an issue with public transport being closed. The admit card will not help us from not contracting the virus 5)We have learnt from the other exams and NTA is prepared to conduct this exam. We have seen the SOPs turn into substandard ones elsewhere. When the exams haven’t been taken when the cases were relatively low, on what basis will we be doing it now? Also is the NTA liable for the health of all the students and take liability? 6) Some students are anxious and want the exams to be over. Here we’ll have a look at the consensus and also not suffering from this deadly virus should be the priority 7)The candidates who have contracted the virus will be not be allowed for the exams. Will they be given an opportunity next year? Also symptoms appear around 14 Days after the infection. How can you ensure that all those at the centre dont have Covid and will not spread it to neighbouring students. 8) Masks , sanitizers etc will be used How can one wear masks for 3 hours in an air conditioned room who wear glasses. What if someone cheats like last time in the January session 9)Recovery Rate is increasing Someone with a good knowledge of Mathematics can say that is obvious and more importantly the number of deaths per day is only increasing. 10)What is the guarantee that the vaccine will be out or the cases will decrease We are not looking to give the exams until the cases peak which according to mathematical model which have worked all around the world will happen even if the vaccines are not out. Any student will not be able to appear for the exam with their full potential unless the situation is conducive instead of a farce SOP. I would like to conclude that we students neither have money nor power. We request you to accept our humble but obvious request. We will never forget these extra ordinary times Thanking you in anticipation , Yours truly,
I would like to request the Physics Galaxy team to please upload the schedule of uploading the checklists.....it will help us to accommodate our routine according to the uploading schedule.....it is very important..... it's a request
Its difficult to share the schedule as Ashish sir is extremely busy and whenever he gets time he records the video and then editing team of PG processes and uploads

1:08:27 sir here 12.9 is greater then 12.75 so in case of photon the transition should happen and remaining 0.15eV should be used as Kinetic energy like what happens in photoelectric effect Or a photon should be emited of energy 0.15ev as failed transition to n=5 If both not then do only photons of exact energy to the decimal points only can cause inner transition as Higher energy may cause ionization
It's excitation energy not ionisation energy so electron cannot afford any extra kinetic energy in the fixed energy orbit. And second point photos are quantized particles means it cannot be divided any further thus 0.15 ev can't be radiated

Case diary
Dear authority,
Name
Parents name:
Application number:
I request you to postpone the Jee and Neet exams in light of the covid-19 pandemic. It is common knowledge that that conditions are not feasible for conducting such big exams.
I request you to schedule the exams once we have crossed the peak of the pandemic and we are ready to bear any delay.
I shall outline why it should be done with accurate arguments.
1) We have prepared SOPs with recommendations from experts in the field and have ratified it with the ministry.
We know that this is an airborne virus. Mask dont help; ministers and officials who follow strict protocol have fallen victim. More so the SOP may be followed at the exam centre but would be useless during travel from home to the centre and back. Even a few students contracting the virus and then spreading it to others who might die or suffer from permanent lung damage.
2) The exams have already been postponed twice earlier and hence we haven’t been insensitive to the student fraternities demand.
But the peak has yet not come and unless that happens our demands have not been met and the actions taken till now will be deemed hollow.
3) We are trying to ensure smooth transition of the academic year.
But at what cost? Someone’s health is any day more important than the academic year. This is something that has affected the whole globe, we can very well afford to take a step back and consider extreme relaxation for extreme situations.
This is a rare phenomena, and taking exams during this time is a punishment.
4) Admit Cards will be used as a pass to traverse through restricted areas.
But for what? Travelling is an issue with public transport being closed. The admit card will not help us from not contracting the virus
5)We have learnt from the other exams and NTA is prepared to conduct this exam.
We have seen the SOPs turn into substandard ones elsewhere. When the exams haven’t been taken when the cases were relatively low, on what basis will we be doing it now? Also is the NTA liable for the health of all the students and take liability?
6) Some students are anxious and want the exams to be over.
Here we’ll have a look at the consensus and also not suffering from this deadly virus should be the priority
7)The candidates who have contracted the virus will be not be allowed for the exams.
Will they be given an opportunity next year?
Also symptoms appear around 14 Days after the infection. How can you ensure that all those at the centre dont have Covid and will not spread it to neighbouring students.
8) Masks , sanitizers etc will be used
How can one wear masks for 3 hours in an air conditioned room who wear glasses. What if someone cheats like last time in the January session
9)Recovery Rate is increasing
Someone with a good knowledge of Mathematics can say that is obvious and more importantly the number of deaths per day is only increasing.
10)What is the guarantee that the vaccine will be out or the cases will decrease
We are not looking to give the exams until the cases peak which according to mathematical model which have worked all around the world will happen even if the vaccines are not out. Any student will not be able to appear for the exam with their full potential unless the situation is conducive instead of a farce SOP.
I would like to conclude that we students neither have money nor power. We request you to accept our humble but obvious request. We will never forget these extra ordinary times
Thanking you in anticipation ,

Infact it is a good revision to the chemistry atomic structure chapter also🙂
1:08:27 sir here 12.9 is greater then 12.75 so in case of photon the transition should happen and remaining 0.15eV should be used as Kinetic energy like what happens in photoelectric effect
