As the frequency of electromagnetic waves increases, the wavelength decreases. This is because the speed of electromagnetic waves in a vacuum is constant (approximately 299,792 kilometers per second), and the relationship between frequency (f), wavelength (λ), and speed (c) is given by the equation:

\[ c = f \cdot \lambda \]

If the frequency increases while the speed remains constant, the wavelength must decrease. Thus, the correct answer is:

**It decreases.**
