How do the values for frequency, period, and wave speed compare? Question 19 options: a) The velocity of a wave is equal to the frequency divided by the period. b) The frequency is the inverse of the period, and the velocity is equal to the wavelength divided by the period. c) The speed of a wave is equal to the frequency times the period. The frequency measures the distance a wave travels, and the period is the inverse of the time taken for a cycle. d) Frequency and period are equivalent, and the speed of the wave is determined by the wavelength times the period.
