SUMMARY
The apparent speed of a goldfish swimming at 4.40 cm/s in an aquarium is calculated using the formula p = - (n1/n2) q, where the index of refraction for water is 1.333 and for air is 1.00. The user initially miscalculated the image distance by switching the object and image distances. The correct application of the formula yields an apparent speed of 5.85 cm/s, which was incorrectly derived due to this mix-up. Proper understanding of the indices of refraction and their application is crucial for accurate calculations.
