I'm taking it that this is a question that is related to library science? If so, then the information that it should document should be the author of the book that is presented, the title of the work, and who published such work. This is to make convenient tracking or retrieval of the document wished to obtain.
Even though the wave speed is calculated by multiplying wavelength by frequency, an alteration in wavelength does not affect wave speed. Rather, an alteration in wavelength affects the frequency in an inverse manner. A doubling of the wavelength results in a halving of the frequency; yet the wave speed is not changed.
hope this helps you
