Wavelength Calculator

FM radio waves are about 3 meters long - WiFi waves are just 12cm (2.4GHz) or 6cm (5GHz)

Visible light wavelengths range from 380nm (violet) to 700nm (red) - incredibly tiny!

5G mmWave uses 24-47 GHz with wavelengths of 6-12mm - hence 'millimeter wave'

X-rays have wavelengths around 0.01-10 nanometers - small enough to image atoms

The lowest piano note (A0) creates a sound wave 12.5 meters long in air

Ocean waves can have wavelengths over 200m, while ripples are just centimeters

Your phone uses multiple wavelengths: cellular (15cm), WiFi (12cm), Bluetooth (12cm)

The Sun's peak emission is at 500nm - green light, though it appears white to us
