Photoelectric Effect The photoelectric effect is the phenomenon that the electrons pop out when a light beam incident on a metal surface. It can be thought that the energy of light is transformed into the form of electrical energy. However, … more

What is the main frequency of the sound around us? Please allow the simulation to request microphone access. If you have set up the microphone or refreshed the webpage screen, touch anywhere on the screen once. 2023.09.20 Update: A function … more
The sensing part is slightly different depending on the frequency of sound. Move the slide bar to check. Cochlear Inside our ears, there is a sensory organ that senses sound. The overall shape resembles a snail called ‘cochlear.’ The cochlea … more
This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of movements that repeated the same oscillation. Like below, shaky or suspended objects are doing this oscillation. Clock pendulum An object suspended in … more
* Above simulation adjusted the amplitude and wavelength for easy observation. * For your understanding, the frequency modulation range of FM broadcasts is exaggerated. Radio frequency The audible frequency is commonly referred to as ‘sound.’ Sound’s frequency range is about … more
