Answer to the Question: Does the fundamental have the highest or lowest fequency?

You answered that the fundamental has the highest frequency.

Examine the figure below which shows both the fundamental frequency and the 25th harmonic. The higher the frequency the more cycles will occur so in this figure the 25th harmonic has the highest frequency and the fundamental will be the lowest frequency for the squarewave grating. In fact, it is most common for the fundamental to be the lowest frequency.

Thus the correct answer was that the fundamental has the lowest frequency.
