Study Notes
Wireless Communication
- The key principle behind wireless communication for devices like Wi-Fi, radios, and cellphones is the transmission of information through electromagnetic waves.
Sound Waves and Communication
- Sound waves are involved in the process of listening to someone's voice through a speaker by converting electrical signals into vibrations that travel through the air as pressure waves.
- These pressure waves, or sound waves, carry the information about the initial disturbance (the speaker's voice) that created them.
Propagation of Sound Waves
- The primary medium through which sound waves propagate to reach the ear is the air.
Common Feature of Wireless Devices
- The common feature among devices like Wi-Fi, radios, and cellphones is that they all use electromagnetic waves to transmit information wirelessly.
