Raadiolaineteks

Raadiolaineteks refers to radio waves in Estonian. Radio waves are a type of electromagnetic radiation with wavelengths longer than infrared light. They are part of the electromagnetic spectrum, which also includes visible light, X-rays, and gamma rays.

Radio waves are generated by oscillating electric charges, such as those found in radio transmitters. They can travel through a vacuum, such as space, as well as through matter. The behavior of radio waves depends on their frequency and wavelength. Higher frequency radio waves have shorter wavelengths and carry more energy.

Radio waves have a wide range of applications. They are used for broadcasting radio and television signals, mobile phone communication, radar systems, and Wi-Fi. Different frequency bands are allocated for specific uses to avoid interference. For example, AM and FM radio use different frequency ranges, and mobile phones operate in specific microwave bands.

The study and use of radio waves fall under the field of radio science, which encompasses radio astronomy, radio engineering, and telecommunications. Understanding the properties of radio waves is crucial for designing and implementing various communication and sensing technologies.
