Formulas
2. Sound: Stationary Source and Moving Source/Observer
λ = v/n
λ' = (v - v_s)/n
n' = n(v/(v - v_s))
n' = n(v/(v + v_s))
n' = n((v + v_o)/v)
3. Reflected Sound and Non-Collinear Motion
n1 = n(v/(v - v_c))
n_ap = n((v + v_c)/(v - v_c))
n_ap = n[(v + v2 cosθ2)/(v - v1 cosθ1)]
4. Light: Doppler Effect and Doppler Shift
n' = n√[(1 + (v/c))/(1 - (v/c))]
n' = n√[(1 - (v/c))/(1 + (v/c))]
Δλ = (v/c)λ
