My HKDSE Physics Deck
Physics
Hi, I took the 2025 DSE, and I made an Anki deck to help me with Physics. Perhaps you might find it useful.
This deck focuses on the memorization part of DSE Physics, and most of it is from Book 3, E2 and E3. There's also some Book 1 and 5 material in here.
Book 2 and 4 (mechanics & electromagnetism) are typically the hardest topics in the subject, but they're more about concepts than memorisation, so I didn't really focus on them here. You should absolutely focus on understanding those concepts first before going for this deck.
This deck goes over:
- Books 1, 3, 5, E2 (Atomic World) & E3 (Energy)
- A little bit of Book 4 (mostly just domestic electricity & a.c.)

17/7/25 Update: Got 5** in Physics. I can't tell you how much of that was due to this deck, though.
Sample Data
| Front | Explain emission spectra with Bohr's model |
| Back | When an atom moves from a higher energy level to a lower one, a photon w/ energy equal to the energy diff. between the energy levels is emitted. (Ephoton = E2 - E1)Since ENERGY LEVELS ARE QUANTIZED,the energy / λ / f of the photons emitted can only take on some discrete values.These show up on the emission spectrum as discrete lines of light. |

| Front 2 | Explain absorption spectra with Bohr's model |
| Back 2 | [Strong white light source] gives out a continuous spectrum.As the light passes through the [energised monoatomic gas],photons of [λ/f] are absorbed to excite the [gas] to higher energy levels.When the excited atom returns to the original state, photons of these [λ/f] are emitted in all directions,so the intensity of the [λ/f] light in the original direction significantly decreases,causing them to appear as dark lines. |
