Final answer:
Gamma rays hold the record for having the shortest wavelengths and highest frequencies compared to other electromagnetic waves such as radio waves, light waves, and infrared waves.
Step-by-step explanation:
The electromagnetic waves with the shortest wavelengths and highest frequencies are known as gamma rays. Gamma rays have wavelengths no longer than 0.01 nanometer, and they can be produced by high-energy astronomical events and decay of radioactive materials. They are at the high-energy end of the electromagnetic spectrum, which also includes radio waves, infrared waves, visible light, ultraviolet light, and X-rays. Because of their high energy, gamma rays can pose a significant health hazard to living tissues.
In summary, the types of electromagnetic radiation in order of increasing frequency are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of electromagnetic radiation has applications and characteristics specific to its frequency and wavelength.
