Experimental error for the travelling microscope

    Whats the scale reading error for a travelling microscope

    Hi

    At school we done an experiment to determine the refractive index of a liquid using real and apparent depth.

    We used a travelling microscope a glass beaker and a coin.

    One question we got was what was the scale reading error for the travelling microscope we used.

    Can anyone help?

    Thanks

    Probably not without seeing the microscope!

    Next time you're in school, have another look at the microscope's scale, and work out the error from that.

    The scale reading error is the error in reading the scale!
    If the scale had 1mm markers and you estimated the position to 0.5mm the scale error would be +-0.25mm,
