This simulation analyzes the sound around you and displays it as a spectrum. We listen to the orchestra and categorize the instruments used in real-time. Listening to orchestral music and categorizing instruments in real-time is quite challenging. This is because...
Tuning fork The tuning fork has a structure that combines the ends of two sticks. When the tuning fork is vibrated, the tuning fork repeatedly approaches and then moves away from each other. The vibration mechanism is simple, so it...
Investigation inside the Earth The surest way to see what the Earth is like is to penetrate and see it yourself. However, there is a limit to penetration because the temperature and pressure rise as you enter the Earth. Therefore,...
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.
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...
Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric field component of light...
Water Wave When you throw a stone into a calm lake, a circle of concentric waves is created and spreads around. The phenomenon that vibration created in one place spreads to the surroundings is called a wave. If you make...
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 the loudness of the sound....
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 move. Not all waves...
