False. Correction: The frequency of radiation decreases as the wavelength increases (or vice versa).
Work Step by Step
The problem with the frequency and wavelength of radiation is that they are inversely related to each other. Considering the following equation (you should remember this one): $\lambda\times\nu = c$ $\lambda$ : wavelength of radiation $\nu$ : frequency of radiation $c$ : speed of light (constant) Since the speed of light is a constant number in a given medium, the frequency of radiation would decrease as the wavelength increases, or vice versa. Therefore, the statement is false.
