Final answer:
Electromagnetic radiation ranges from high-energy gamma rays and X-rays, to mid-range visible light, and extends to low-energy radio waves. The differences in their wavelengths and frequencies correspond to various levels of energy.
Step-by-step explanation:
The term you're looking for is electromagnetic radiation. This spectrum encompasses all forms of electromagnetic waves, which vary in wavelength, frequency, and energy. At the high-energy end of the spectrum are gamma rays and X-rays, which have the shortest wavelengths and the highest frequencies, making them particularly potent and potentially hazardous to living organisms. Gamma rays can have wavelengths as short as 10-16 meters. Following these are ultraviolet rays, which are emitted by the sun and can cause sunburns or skin cancer. The spectrum then moves to the visible light range, responding to the frequencies that our eyes can detect, and extends further to include infrared radiation and radio waves. Visible light lies in the range of 400 to 700 nanometers (nm), whereas radio waves can measure up to several hundred meters in length.
