Study Notes
Wave Characteristics
- A wave's ability to carry information is due to its amplitude, frequency, and phase, which can be modulated to encode information.
Sound Waves in Wireless Communication
- Sound waves are involved in wireless communication for devices like cellphones through a process called modulation, where sound waves are used to transmit information through the air as radio waves.
Principle behind Wireless Communication
- The key principle behind wireless communication for devices like Wi-Fi, radios, and cellphones is the transmission and reception of radio waves, which carry information through the air.
Sound Wave Propagation
- Sound waves propagate through the air as a medium to reach the human ear, allowing us to hear and perceive sound.
Information Carried by Waves
- The initial disturbance that created a wave determines the information it carries, and the wave's characteristics, such as amplitude, frequency, and phase, allow it to convey this information.
