Electromagnetic Spectrum
Electromagnetic Spectrum refers to the range of all types of electromagnetic radiation. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of radiation has a different wavelength and frequency, and they all travel at the speed of light. Electromagnetic Spectrum plays a crucial role in space and astronautical engineering as it is used for communication, remote sensing, and imaging. Radio waves are used for communication with spacecraft and satellites, while microwaves are used for weather forecasting and remote sensing. Infrared radiation is used for thermal imaging, and visible light is used for optical imaging. Ultraviolet radiation is used for studying the properties of stars and galaxies, and X-rays and gamma rays are used for medical imaging and studying high-energy phenomena in space.
