    Well this may sound bad, but "how long is a piece of string". You haven't given us much information about the experiment as a whole but I would say as many wavelengths as you have time to do and as many repeats would give the most accurate/ statistically relevent data. But I would say 5 wavelengths and 6 repeats would be more than enough to draw a reasonable conclusion. You could probably get away with 3-5 repeats depending on how close the data points are within eachother.

    Hope that helps.
