Final answer:
Electromagnetic radiation types ranked by increasing frequency are: radio waves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays, with radio waves being the lowest and gamma rays the highest in frequency.
Step-by-step explanation:
To rank the different types of electromagnetic radiation by their frequency, with the lowest frequency at the top, we have:
- Radio waves
- Infrared light
- Visible light
- Ultraviolet light
- X-rays
- Gamma rays
Electromagnetic radiation is categorized by frequency, and this spectrum ranges from radio waves, which have the lowest frequency, up to gamma rays, which have the highest frequency. Radio waves are often used in various wireless communications and are categorized as the lowest frequency EM waves. Infrared light falls below visible light in frequency and is typically emitted by the thermal motion of particles. Visible light encompasses the spectrum that is detectable by the human eye, with red having the lowest frequency and violet the highest within this range. Ultraviolet light starts just above the violet end of the visible spectrum and is commonly associated with electronic transitions in atoms. X-rays are high-frequency waves used in medical imaging and other applications, while gamma rays are the highest frequency waves and are often the product of nuclear reactions and other high-energy processes.
