Phase 1: Comprehending the Electromagnetic Spectrum.
The electromagnetic spectrum is ordered by frequency and wavelength. The progression from lowest frequency (longest wavelength) to highest frequency (shortest wavelength) is: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Phase 2: Analyzing the Provided Choices.
Radio waves exhibit the longest wavelengths and lowest frequencies among the listed options.
Microwaves possess higher frequencies than radio waves but are still considerably lower than infrared radiation.
Infrared radiation has higher frequencies than radio waves and microwaves but lower than visible light.
Gamma rays are situated at the extreme upper end of the spectrum, characterized by the shortest wavelengths and highest frequencies.
Phase 3: Determining the Option with the Highest Frequency.
Based on the sequence of the electromagnetic spectrum, gamma rays are definitively identified as having the highest frequency among the presented options.
