ELECTROMAGNETIC SPECTRUM Increasing Wavelength (m) Increasing Frequency (Hz) = = Radio waves are a type of electromagnetic radiation used to transmit signals for communication, such as radio Infrared radiation is sometimes called "heat radiation" because we feel it as warmth. TV remote controls use infrared Ultraviolet radiation is a type of electromagnetic radiation from the Sun that can cause sunburn and is used in Gamma rays are a type radiation that are highly energetic and are produced by radioactive materials and television. Microwaves are a type of electromagnetic radiation that heats food and is used in microwave ovens. radiation. Visible light is the type of electromagnetic radiation that allows us to see colors and the world around us. blacklights. and nuclear reactions. X-rays are a type of radiation that can pass through our bodies and are used to create images of our bones. Benefit and Uses of Electromagnetic Spectrum The uses of the microwave are similar to that of radio waves. They are used in communications, radio Radio waves are widely used gstronomy, remote for communication, including sensing, radar, and of television broadcasting, and heating application, mobile phones. They also play _ they are used in Infrared radiation is utilized in night vision technology, thermal Visible light can sufficiently inactive viruses. Increased sensitivity was observed with enveloped viruses (such as coronaviruses) compared to non- . X-rays are commonly employed in medical imaging, including X- ray radiography, computed tomography (CT) scans, and fluoroscopy, providing Gamma rays have valuable insights into applications in the internal structures medical treatments, of objects. Ultraviolet (UV) radiation has applications in sterilization particularly in cancer a crucial role in radar systems for navigation and weather monitoring. cooking as well. “= ay 2 oon — imaging cameras, and remote controls for electronic devices rt yy Ie enveloped medical equipment. UV light is also used in forensic investigations and certain types of industrial processes. processes, such as in water treatment and therapy (radiotherapy). They are also used in industrial radiography for inspecting the integrity of materials and in some types of scientific research.
