Does frequency affect period?
Does frequency affect period? The Relationship between Wave Frequency, Period, Wavelength, and Velocity. just as in the case of harmonic motion of an object. We can see from this relationship that a higher frequency means a shorter period. Recall that the unit for frequency is hertz (Hz), and that 1 Hz is one cycle—or one […]
