Wi-Fi relies on radio waves in the UHF and SHF bands, operating primarily on 2.4 GHz, 5 GHz, and 6 GHz frequencies.
Because frequency and wavelength are inversely related, higher frequencies equate to shorter, faster, and more localized waves.Wi-Fi Wavelength Breakdown2.4 GHz Band: Approximately 12 cm (4.7 inches). This longer wavelength is ideal for passing through solid obstacles
(like walls and floors) and provides broader coverage.5 GHz Band: Approximately 6 cm (2.4 inches). Shorter waves allow for much faster speeds and less interference,
but they struggle to penetrate dense walls.6 GHz Band: Approximately 5 cm (2.0 inches). Used by newer Wi-Fi standards (like Wi-Fi 6E and 7), this band provides ultra-high speeds and massive capacity but has the shortest range and is easily blocked by physical barriers.
와이파이(Wi-Fi) 전파는 눈에 보이지 않는 전자파이며, 주로 2.4GHz와 5GHz 주파수 대역을 사용합니다. 주파수가 높을수록 파장의 길이가 짧아지며, 각 파장의 특성에 따라 연결 범위와 속도가 달라집니다.1. 2.4GHz 대역파장 길이: 약 12.5cm특징: 파장이 길어 장애물을 잘 통과하고 넓은 범위로 신호가 전달됩니다.
1. 2.4GHz 대역파장 길이: 약 12.5cm특징: 파장이 길어 장애물을 잘 통과하고 넓은 범위로 신호가 전달됩니다.단점: 벽을 통과하는 회절력은 좋지만, 전자레인지나 블루투스 등 다른 가전제품과 주파수가 겹쳐 신호 간섭이 발생하기 쉽고 속도가 상대적으로 느립니다.2.
5GHz 대역파장 길이: 약 6cm (2.4GHz 대비 절반 수준)특징: 파장이 짧아 데이터 전송 속도가 매우 빠릅니다. 와이파이 전용 주파수를 사용하여 주변 기기로 인한 간섭이 적습니다.단점: 파장이 짧아 벽이나 가구 같은 장애물을 만나면 신호가 쉽게 약해지거나 도달 거리가 짧아집니다.

Can humans see 700 nm?
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.Aug 4, 2023

Infrared light can be detected by the human eye after allNo, humans cannot see microwave wavelengths. Our eyes can only detect a tiny sliver of the electromagnetic spectrum called visible light, which ranges from roughly 380 to 700 nanometers. Microwaves are much longer, ranging from about 1 millimeter to 1 meter.

The reason we are blind to them comes down to both physics and biology:
No Biological Receptors: The photoreceptors in our retinas (cones and rods) are designed to react only to the specific energy levels of visible light. Microwave
The Broader Electromagnetic SpectrumLight acts as both a wave and a particle. Beyond the visible band, electromagnetic radiation extends into shorter and longer wavelengths, as outlined by NASA Science:Shorter than 380 nm: Ultraviolet, X-rays, and Gamma raysLonger than 750 nm: Infrared, Microwaves, and Radio waves
