Waves - Coggle Diagram
Waves
Radio
Type: Transverse, electromagnetic, long wavelength, low frequency
Pros: Long distance, safe, versatile
Uses: Radio, TV, mobile phones, data transmission
Cons: Weakens over distance, interference, blocked by obstacles
Micro
Type: Transverse, electromagnetic, non-ionising, longer than light
Pros: Long distance, safe, versatile
Uses: Radio, TV, mobile phones, data transmission
Cons: Weakens over distance, interference, blocked by obstacles
Infrared
Pros: Safe, secure (no through walls), reliable short range
Cons: Needs line-of-sight, absorbed by atmosphere, short distance
Type: Transverse, electromagnetic, longer wavelength than visible light
Uses: Remotes, sensors, short-range wireless devices
Visable light
Type: Transverse, electromagnetic, visible part of spectrum
Pros: Very fast, safe, works where radio can’t (hospitals, planes)
Uses: Li-Fi (LEDs flashing to transmit data), optical signals
Cons: Blocked by walls, needs clear sight, poor in sunlight
