Examine the diagram of the electromagnetic spectrum below. Diagram of electromagnetic spectrum. Gamma waves have wavelengths of approximately 10 to the power of negative 12 meters. x-rays have wavelengths of approximately 10 to the power of 10 meters. Microwaves have wavelengths of approximately 10 to the power of negative 2 meters. Radio rays have wavelengths of approximately 10 to the power of 3 meters.

If a wave has a wavelength of 0.1 nanometer, it must be a(n)
