Answer to the Question:Does the amplitude of the components get greater or smaller as frequency goes up?

You answered that the amplitude gets smaller as frquency goes up.

Examine the figure below which shows the amplitudes and frequencies for each of the first 13 frequencies that make up a squarewave. The amplitude is shown by the height of the bar and the relative frequency is shown by the numbers under each bar. As the number goes up so does the relative frequency and so as frequency goes up the bars get smaller and,

thus, your answer is CORRECT.
