Pendulum wave A ‘Pendulum wave’ is a collective wave-like phenomenon that appears when pendulums (weights) of different lengths are arranged side by side. Because each pendulum has a different period depending on its length, they oscillate … more
Hz Height and loudness of the sound When we often say that a sound is ‘low’ or ‘high,’ we are referring to the height of the sound. The height of the sound is completely different from … more
Waves in spring When the left end of the spring vibrates, the vibration is transmitted to the other end. A spring can vibrate horizontally or vertically. Fixed-end reflection When a wave reflects off a fixed-end, the … more
Reset Wave In science, a wave is a phenomenon in which energy is transmitted through a medium. It is the only energy that is transmitted through the wave. The medium only vibrates but does not actually … more
Spinning radar In general, electromagnetic waves (radio waves) propagate in all directions. In this case, radio waves can be transmitted or received in any direction. However, as the distance increases, the strength of the radio wave … more
