Symbol help - Mirrors & units question

    Symbol help -- Mirrors & units question

    Calculate to the nearest 0.1000 degree the diffraction angle of the first order image produced by monochromatic light of wavelength 5890.0 A as the light passes through a grating of 5500.0 lines/cm.

    WHAT DOES THE SYMBOL 'A' MEAN?!?!

    My guess was 1^-10 but i can't find it on google.

    So would it be 589nm?

    Thanks!

    It's probably the symbol for Angstroms: http://en.wikipedia.org/wiki/Angstrom
