!Ignotum/Formulae/Wave
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

# Physics > Waves c=fl Where: c=wave speed f=frequency l=wavelength c=x(k/m)^� For compression waves in a mass-spring system: c=wave speed x=spacing, m=mass k='spring' constant c=(E/d)^� For a sound wave in a solid: c=wave speed E=Young modulus d=density c=(T/u) For a transverse wave in a string: c=wave speed T=tension force u=mass per unit length c=1/(eu)^� For electromagnetic waves in free space: c=wave speed e=permittivity of free space u=permeability of free space l=sx/L In Young's fringe experiment: l=wavelength s=slit spacing x=fringe separation L=distance from slits to fringes
