electromagnetic waves
they are basically used by all types only some have different names and are a type of it
Like wireless is : Hertzian waves (electromagnetic waves) well the elctormagnetic waves can smd!
Many different types can be:sound waves in airelectrical waves in wireselectromagnetic waves (e.g. radio, microwave, infrared, visible light)etc.
Cell phones use radio waves for communication.
Electromagnetic waves used for communication include radio waves, microwaves, and light waves (in the form of lasers). These waves are commonly used in technologies such as radio communication, satellite communication, Wi-Fi, and fiber optic communication.
Two types of waves based on wavelength are ultraviolet waves with short wavelengths and radio waves with long wavelengths. Ultraviolet waves have higher frequencies and carry more energy, while radio waves have lower frequencies and are commonly used for communication.
Radio waves and microwaves are both used for communication through technologies such as mobile phones, Wi-Fi routers, and satellites. Radio waves are commonly used for long-range communication, while microwaves are more often used for shorter-range communication and can carry higher data rates. Both types of waves are able to transmit information wirelessly by modulating their characteristics to encode data.
Cell phones use radio waves for communication.
radio waves are used in tv communication, weather broadcasting
Radio waves have long wavelengths and carry energy that can be used for communication, such as radio and television broadcasting. These waves are also used for various types of radar and remote sensing applications.
You use sound waves to communicate.
All sound waves are longitudinal (compression/rarefaction) waves.
light waves
so you can communicate with others
