The energy of microwaves is less than the energy of ultraviolet light. which comparison of the energies of electromagnetic waves is correct?
a x-rays have lower energy than gamma rays because x-rays have higher frequencies.
b x-rays have lower energy than gamma rays because x-rays have shorter wavelengths.
c visible light has higher energy than infrared light because visible light has longer wavelengths.
d visible light has higher energy than infrared light because visible light has higher frequencies.
