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.**
\[ c = f \cdot \lambda \]
If the frequency increases while the speed remains constant, the wavelength must decrease. Thus, the correct answer is:
**It decreases.**
