Na rarama e electromagnetic rarama ena loma ni dua na tiki ni electromagnetic karakarawa. Na vosa e dau tukuna na rarama, sai koya na tiki ni mo e rawa ni kilai mai na mata ni tamata. Na rarama e laurai e dau vakamacalataki me vaka na wavelengths ena 400 – 700 nanometers (NM), se 4.00 × 10 − 7 ki na 7.00 × 10 − 7 m, ena maliwa ni infrared (ena wavelengths balavu) kei na ultraviolet (kei na kena e lekaleka wavelengths). Na wavelength oqo e kena ibalebale na roughly 430 – 750 terahertz (THz).

Triangular prism dispersing na kau ni rarama vulavula. Na wavelengths balavu (Damudamu) kei na kena e lekaleka na wavelengths (karakarawa) era veitawasei.
