3Hz refers to 3 cycles or oscillations per second. In the context of sound or light waves, 3Hz would represent a very low frequency. In the human brain, delta brain waves, associated with deep sleep, are typically around 0.5-4Hz.
The formula to calculate the speed of a wave is speed = wavelength x frequency. Plugging in the given values, speed = 18mm x 3Hz = 54 mm/s. The wave travels at a speed of 54 millimeters per second.
The period of the pendulum is the time taken for one complete back-and-forth motion. In this case, since the pendulum takes 3 seconds to move away and 3 seconds to come back, the total time for one full cycle is 6 seconds. Therefore, the period of the pendulum is 6 seconds.
