Ultraungu bermaksud "melebihi ungu" dan dinamakan sebegitu kerana [[frekuensi]]nya melebihi cahaya ungu. Sesetengah haiwan (burung, reptilia, dan serangga seperti lebah) boleh melihat sinar UV dekat. Ini disebabkan kebanyakan buah-buahan, bunga dan bijian kelihatan lebih menyerlah dalam sinar UV berbanding sinar nampak.
