Collection of Formulae excluding nuclear and space physics for IGCSE 0625 in the years 2023 to 2025.
| Front | Refractive Index (angle) = |
| Back | Refractive index (angle) = sine of the angle of incidence, i / sine of the angle of refraction, rn = sin i / sin r |
| Front | Transformers (Turns) = |
| Back | Transformers: voltage in secondary coil (V) / voltage in primary coil (V) = turns on secondary coil / turns on primary coil𝑉s 𝑉p = 𝑁s 𝑁p |
| Front | Refractive index (speed of light) = |
| Back | Refractive index (speed of light) = speed of light in vaccum / speed of light in materialn = c / v |
