De Broglie’s Car Chase

1 de Broglie's Car Chase

According to de Broglie, every particle has an associated wavelength of λ=h/p. The larger the momentum, the shorter the wavelength.

In this comic, the car is desperately trying to increasing its speed and thus momentum, so as to shorten its wavelength, and hopefully avoid being diffracted when it drives through the slit. Haha.

The Wave-Particle Face-off

6 nature of light debate

Is light a wave or a stream of particles? This has been debated for hundreds of years. From Newton’s Corpuscular Theory, to Huygen’s Principle. Young’s double slit experiment seemed to have settled matters, until Einstein’s photoelectric effect came along.

In this comic, pugilists from the wave and particle camps fight each other to the death, throwing deadly wave and particle weapons at each other. Haha.

Continuous Spectrum Violin

8 continuous spectrum violin

A hot solid emits light with a continuous spectrum, i.e. there is no gap in the spectrum, every wavelength is present. A hot gas on the other hand emits light with a discrete spectrum, i.e. only certain sharply defined wavelengths are present.

In this comic, the boy is struggling to play the correct notes because the violin is a “continuous spectrum instrument”. By pressing along the violin string, one can produce sounds of any pitch, including off tune notes. A piano on the other hand is a “discrete spectrum instrument”. It can only produce notes that the piano keys have been tuned to, and nothing in between. Haha.

The Banana Absorption Line

9 fruit absorption line

An absorption spectrum is obtained by shining white light through a dense gas. While most light passes through the dense gas, certain specific wavelengths (that correspond to the energy gaps in the gas atom’s quantized energy structure) are absorbed. The resulting spectrum is best described as dark lines in a continuous spectrum.

In this comic, only the bananas are “absorbed” by the monkey, resulting in gaps in the “fruit spectrum”. Haha.

Bremsstrahlung Car

10 bremsstrahlung car

A charged body undergoing acceleration (speed up, slow down, or change direction) must lose energy by emitting electromagnetic radiation. This is called the Bremsstrahlung radiation, which is the underlying cause for the background X-ray radiation.

In this comic, the car moving in a zig-zag manner is fined for accelerating, losing eV in the process. Haha.

Hydrogens Unite

12 hydrogen fusion

Hydrogen fusion releases a tremendous amount of energy. However, for hydrogen nuclei to come close together, they must first overcome the very strong electrical repulsive forces between the positively charged nuclei. This is why fusion can only occur at high temperature.

This comic depicts a rally for protons to overcome their “differences”, so as to fuse together and shine as a new star is born. Haha.
