Planck's law · Wien's displacement

Controls

Every warm object glows with a Planck spectrum. Heat it up and the peak shifts to shorter (bluer) wavelengths — that's why stars range from red to blue-white.

Temperature5778 K

Peak wavelength502 nm

Colorwhite/yellow

Governing equation

λ_{m a x} = \frac{b}{T} = \frac{2.898 \times 1 0 ^{6}}{5778} = 502 nm

Reading this result: At 5778 K the Planck curve peaks at 502 nm, inside the visible band — Wien's law makes peak wavelength ∝ 1/T, so doubling the temperature halves the peak wavelength and shifts the glow toward blue.

electron probability clouds

Controls

Solving the Schrödinger equation for hydrogen gives the orbitals — the probability clouds where an electron is likely to be found. The quantum numbers n, l, and m set the size, shape, and orientation. Brighter regions are higher probability density.

Governing equation

E_{2} = - \frac{13.6}{2 ^{2}} eV = - 3.40 eV (2 p)

Reading this result: n=2 sets the shell and energy (E = -3.40 eV) and the overall size of the cloud. l=1 sets the shape: two lobes (p). m=0 sets the orientation in space. This orbital has 0 radial nodes and 1 angular node.

About this simulation

The full Spectroscopy Kit tool models a playground swing with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
