我諗你係指Kinetic theory of ideal gas嗰proof
其實2016開始已經cut左嗰proof,
Centripetal acceleration
Kinetic theory of ideal gas
呢兩個proof已經cut左
如果你想知點proof,我都可以再post詳細少少嘅proof

我未係正職老師,
搵教席都係識人緊要d
利申:好多學校物理老師都識
你有興趣,留tg,有時學校搵我教班,
我都要搵人幫手

主要有4 part
Rutherford model
- description of model
- failure to explain some phenomenon
Photoelectric effect
- why particle theory of light should be used instead of wave theory? (有3個experiment results wave theory解釋唔到)
- formulaSSSSSSSS
(KEmax=e Vs = hf - phi)
( light intensity = (#photon/time)(hf)/area ) 呢題都最好當一條式去記
Bohr model
- postulates
- relation of orbit radius of election and energy with quantum number n
(其實計數機constant入面係有Bohr radius ,嗰symbol係a0)
- 點去計數
- transition of energy level can be done by
Absorbing/emitting photon or inelastic collision with electron
wave-particle duality
- equation of wavelength , energy and momentum of wave and particle
- experiment evidence of particle nature of light and wave nature of particle
Nano-scale
- water-repelling vs water-attracting in cleaning
- 計數比較簡單,但要小心
- TEM and STM
1) 想解答所有關於DSE Phy的問題
(有問必答,不過工作繁忙,盡快會覆你)
2) 分享下tips
(每年marking 寛鬆程度都有出入,我以最緊的程度為準)
如果有錯別字,請見諒
自我簡介一下
DSE5**,物理系grad,有出過Mock,改過Mock
上年兩個私補都5**,依家係幾間中學教緊課後物理班
Tip 1
長問題如果有問到某d key word,必須寫啱/串啱key words先會拿到分
常見錯別字(中文)
幅射輻射(差不多一半中文卷考生都寫錯)
唔識串/經常串錯嘅英文字
rarefractionrarefactiontransverse
longitudinal
如果大家反應好,我每日打一篇tips
