• Not enough information to determine

How does the hazard level of electromagnetic waves change as the frequency of the waves increases?

• Energy and wavelength increase; it becomes more hazardous.

• Energy and wavelength decrease; becomes less hazardous.

• Energy decreases, wavelength increases; it becomes less hazardous.

• Energy increases, wavelength decreases; it becomes more hazardous.
