Answer:
D.) Infrared
Explanation:
~ Radiant energy of an electromagnetic radiation is determined by its frequency and wavelength. Higher frequency and lower wavelength has highest radiant energy. On the other hand, lower frequency and higher wavelength produces less radiant energy.
~ Order of frequency from highest to lowest:
x-rays(10¹⁶ Hz to 10¹⁹ Hz) > Ultraviolet (10¹⁴ Hz) > visible (between 430 THz and 770 THz) > infra-red ( less than 430 THz)
So... infra-red which has least frequency would have lowest radiant energy.
