Answer:
C) As wavelength decreases radiant energy and frequency increases.
Step-by-step explanation:
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The trends in an electromagnetic spectrum are such that when Wavelength decreases, the frequency of the radiation Increases. Also, higher frequency radiations tend to have greater energy.
Hence, as wavelength decreases, radiant energy and frequency increases.
