Explanation:

All electromagnetic waves travel at the same speed ($3\times10^8$ m/s) in a vacuum. Amplitude affects wave intensity but not the fundamental type of electromagnetic wave. Wavelength and frequency are inversely related via $c = \lambda f$ (where $c$ is speed, $\lambda$ is wavelength, $f$ is frequency), and these properties define the distinct types of electromagnetic waves (e.g., radio, visible light, X-rays).

Answer:

Wavelength, Frequency
