Wavelet methods have become a very much common tool for exploring and analyzing solar data. Many methods have been developed. I will briefly describe three different methods: Wavelet Power Spectra (WPS), Ampligrams, and Multi-Resolution Analysis (MRA). I will then give examples of how the wavelet methods have been applied to indicators of solar activity. Interestingly these studies raise fundamental questions about what we mean by solar activity and how good the indicators are.
