[J2] Lesson 20 (18 – 24 May) Updates/ Debrief

[J2 Physics PMCians]Wave Particle Duality & the strange Heisenberg’s Uncertainty Principle

 

What we did in 2 hours:

We explored the final installment of Quantum Physics, Wave Particle Duality as shown by de Broglie’s equation, and moved on to look at the strange world of Heisenberg’s Uncertainty Principle. Of course, we understood that these strange phenomena are only observable in the sub-atomic world, not in our macro world. 🙂  

What you take home:

1) Quantum Physics Daily Dose

Please download and print the Daily Dose for your personal revision. The answers and working are at the back:

Please disregard Qn 64 & 65 on Potential Well / Barrier. This has been removed from your syllabus!!

 

2) Quantum Physics Test A & Test B ( 4Q)  (for your reference)

Special Mention:

Gentle reminder that we will begin our PMC Signature J2PH Revision Programme this coming Wednesday (20 May) at 10am.

We look forward to seeing all of you in the Live Lesson!

 

Till then, stay rested and healthy!

What we did in 2 hours:

We finished Sample Mean Distribution and have now covered all the types of distributions in the syllabus. We will apply our Normal and Sample Mean distribution skills to the next chapter, Hypothesis Testing.

 

Also good job completing both of our Additional Lessons! With that our mid-year revision for Sequences & Series as well as Vectors is completed, the rest of the Pure Math topics will be covered through June.

What you take home:

The Take-Away Questions worked solutions and LIVE questions for both SS and Vectors are linked here:

What we did in 2 hours:

What a week, huh? We have completed the last topic of the syllabus – Electrochemistry all within one week! Let us look at what we have covered – 

Electrochemical Cells

  1. The standard electrode potential and how to measure it
  2. The full electrochemical cell
  3. Predicting spontaneity of redox reactions using Ecell and Gibbs’ free energy change
  4. Effect of concentration on E value

 

Electrolytic Cells

  1. Predicting the reactions at electrodes
  2. Calculations involving amount of electrons transferred and Avogadro’s constant
  3. Industrial applications of electrolysis

What you take home:

The solutions to the Everything you need to know series and selected structured questions are found here:

So we have completed syllabus! Next lesson onwards, we will begin our revision for the A Levels!

Meanwhile, do enjoy a real-life demonstration of purification of copper electrolytically!
