frequency spectrum analysis

Hello everyone I have this problem that I'm working on as an assignment for my university: I have to roughly predict what a waveform would look like just by looking at it's frequency spectrum?
Now the waveform doesn't have to be 100% accurate but a rough prediction of what it might look like is required from me. I have studied and read all I can about Fourier transforms but I honestly don't know where to begin and how to approach this subject so I really need any help I can get since it's 50% of my grade from what the professor told me and atm I don't have anything that can at least guide me and searching the internet there is nothing that can help me either.

Re: frequency spectrum analysis

A wave with a high frequency has a short wavelength, so its peaks and troughs are bunched up close together. One with a low frequency will have a longer wavelength, i.e. its peaks and troughs are more spread out.
