Why does a decrease in the frequency of electromagnetic radiation cause the extent of the change in the electrical field at a given point to decrease?

A lower frequency means a longer wavelength. Since the wavelengths are longer, it allows less oscillations to be completed in a time frame compared to a small wavelength. "extent of the change" means the slope so since the wavelength is longer, the slope changes less.
