Units and Measurements

7 entries
Absolute Error = |Measured Value − True Value|
Mean Absolute Error = (Σ|Δa_i|)/n
Relative Error = Mean Absolute Error / Mean Value
Percentage Error = Relative Error × 100
Error in Sum: Δx = Δa + Δb

Ray Optics and Optical Instruments

7 entries
M = 1 + \frac{D}{f}
M = \frac{D}{f}
M = m_o \times m_e
M = \frac{v_o}{u_o} \left(1 + \frac{D}{f_e}\right)
M = \frac{f_o}{f_e}
