U2-1 Sound Vibrations
Images of sound
In this station, we learn how to photograph sound waves.
Zu Station U2-1U2-2 Interference of Sound
Classical waves
How do classical waves propagate through space? An observer looks at the possible paths of sound waves. What happens when waves from different paths overlap at the observer’s position?
Zu Station U2-2U2-3 Overtones
On the mixture of frequencies
In this station, we explain frequency analysis and Fourier analysis, respectively.
Zu Station U2-3U2-4 Standing Waves
On vibrating strings
In this station, we discuss the connection between nodal points and the overtone spectrum of a string.
Zu Station U2-4U2-5 Spherical Vibrations
On vibrating spherical surfaces
In this station, we discuss standing waves in one and two dimensions and the transformation of nodal points to nodal lines.
Zu Station U2-5U2-6 Quantum Mirror
On Planck’s constant as a quantum of nodal lines
In this station, we discuss the transition from observable standing waves to quantum states.
Zu Station U2-6U2-7 Spin
On the mirror in the middle
A small displacement of the mirror causes a giant leap into a new dimension.
Zu Station U2-7U2-8 Atomic Models
From Bohr to the quantum dimension
In this station, we compare the Bohr model with the model of quantum reflections and show that we can understand the structure of the periodic table by counting the nodal lines of quantum states.
Zu Station U2-8U2-9 Quantum Organ
On the dance of electrons
In this final station of the U2 subway line we show selected examples of quantum melodies.
