A collection of the most valuable formula for CCEA Physics AS2
This is a draft cheat sheet. It is a work in progress and is not finished yet.
2.1 Wavesf = T-1 | Frequency = Period Time of Wave -1 | v=fλ | Velocity = Frequency x Wavelength |
2.2 Refractionn = (sin i)÷(sin r) | Refractive Index = (sin [Incident Ray])÷(sin [Refracted Ray]) | n =(c1 )÷(c2 ) | Refractive Index = (Velocity Before Refraction)÷(Velocity After Refraction) | sin c = n-1 | sin (Critical Angle) = Refractive Index -1 |
Lensesf-1=u-1+v-1 | (Focal Length)-1 = (Object Distance)-1+(Image Distance)-1 | f-1=P** | (Focal Length)-1 = Power of Lens | m= (hi )÷(ho ) | Magnification = (Height of Image)÷(Height of Object | m= (v)÷(u) | Magnification = (Image Distance)÷(Object Distance) |
2.4 Superposition, Interference and Diffractionλ=(ay)÷d | Wavelength = Slit Separation x Fringe Separation ÷ Distance to Screen | dsinϑ=nλ | (Slit Spacing)sin(Angle From Centre) = (Order of Maxima) x Wavelength |
