radio waves
Examples of transmission waves include radio waves, microwaves, infrared waves, and visible light waves. These waves are used to transmit information and energy through various mediums.
Radio waves - in the microwave section of the electromagnetic spectrum.
Devices that use radio waves for communication and transmission include smartphones, radios, televisions, Wi-Fi routers, and satellite communication systems.
Cellphones use radio waves for transmission and reception of signals. These waves are a type of electromagnetic radiation that falls within the radio frequency range.
Sound waves require a medium, such as air, water, or solids, for transmission. Light, radio, and infrared waves can travel through a vacuum and do not require a medium for transmission.
