Wayne is correct but the ~ sign is indicating 'frequency', which nowadays uses the unit Hertz (Hz). The specification that it is AC current is covered by the written 'AC'. You can't use wavelength to describe AC electricity. Wavelength applies to radio waves and waves in the sea. The longer the wavelength, the lower the frequency is.

If the 60 referred to current it would have 'A' (for Amps) after it. DC current does not have a frequency so would not need that line of information.
