Frequently Asked Questions
How are wavelength, frequency, and energy related?
c = λf (speed of light = wavelength × frequency) and E = hf (energy = Planck's constant × frequency). Shorter wavelength means higher frequency and more energy. These relationships apply to all electromagnetic waves.
What are the regions of the electromagnetic spectrum?
From low to high frequency: Radio (< 3 GHz), Microwave (3 GHz - 300 GHz), Infrared (300 GHz - 430 THz), Visible (430-750 THz), Ultraviolet (750 THz - 30 PHz), X-ray (30 PHz - 30 EHz), Gamma Ray (> 30 EHz).
