The best description of the relationship between wavelength and frequency in an electromagnetic wave is **inversely proportional**.

As the frequency of the wave increases, the wavelength decreases, and vice versa. This relationship can be expressed by the equation:

\[ c = \lambda \cdot f \]

where \( c \) is the speed of light, \( \lambda \) is the wavelength, and \( f \) is the frequency. Since the speed of light is constant, an increase in frequency results in a decrease in wavelength, indicating their inverse relationship.
