Recall the fundamental relationship between the speed of light (c), wavelength (\lambda), and frequency (\nu) of electromagnetic radiation, which is given by the equation:
\(c = \lambda \times \nu\)
Understand that the speed of light (c) is a constant value in a vacuum, approximately \(3.00 \times 10^{8}\) meters per second.
Since $c\( is constant, if the wavelength (\lambda) increases, the frequency (\nu) must decrease to keep the product \)\lambda \times \nu$ equal to \(c\).
Conversely, if the frequency (\nu) increases, the wavelength (\lambda) must decrease, showing an inverse relationship between wavelength and frequency.
Therefore, the correct description is: 'As wavelength increases, frequency decreases,' because wavelength and frequency are inversely proportional.
