SUMMARY
The focal length (F) can be calculated using the formula 1/L + 1/U = 1/F, where L is the object distance (60 cm) and U is the image distance (31 cm). To find the uncertainties in the measurements, one must apply error propagation techniques relevant to the formula used. This discussion emphasizes the importance of understanding both the calculation of focal length and the associated uncertainties in optical measurements.
