The Electromagnetic Spectrum Flashcards

All 3 cards in this deck

Name the seven groups of the electromagnetic spectrum in order of increasing frequency.

Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.

Name the colours of the visible spectrum in order of decreasing wavelength.

Red, orange, yellow, green, blue, indigo, violet.

What does it mean that the electromagnetic spectrum is continuous?

There are no gaps between the groups — wavelength decreases and frequency increases smoothly from radio waves to gamma rays.
