SUMMARY
The correct velocity of a standing wave oscillating at 100 Hz is determined using the formula Velocity = (wavelength) x (frequency). The wavelength provided in the discussion is 20 x 10-2 meters, which converts to 20 cm. However, the calculation of velocity as 20 meters per second is incorrect due to unit inconsistency. The correct approach requires ensuring that all measurements are in the same unit system, specifically meters.
PREREQUISITES
