Radio waves and infrared radiation, characterized by longer wavelengths and lower frequencies, carry the least energy among electromagnetic waves. Their unique properties enable diverse applications in communication, broadcasting, thermal imaging, and remote sensing.
Low-frequency electromagnetic waves that carry the least energy include radio waves and infrared radiation. These waves exhibit longer wavelengths and lower frequencies compared to other forms of electromagnetic radiation like visible light, ultraviolet, X-rays, and gamma rays.
Radio waves typically have frequencies ranging from a few hertz to several gigahertz, with corresponding wavelengths ranging from kilometers to millimeters. Due to their longer wavelengths and lower frequencies, radio waves are less energetic than other forms of electromagnetic radiation.
Similarly, infrared radiation lies just beyond the visible spectrum, with frequencies lower than those of visible light. While infrared radiation is associated with heat and is commonly used in technologies like thermal imaging, it still possesses lower energy compared to higher-frequency waves.
The varying energy levels across the electromagnetic spectrum make each type of wave suitable for different applications, ranging from communication and broadcasting with radio waves to thermal imaging and remote sensing with infrared radiation.
