Visible waves.

Human eyes detect light in the visible spectrum, roughly about 380–750 nm (often quoted as 400–700 nm). Infrared and ultraviolet are outside that range (generally not seen by humans, though very-near-UV/near-IR can be detected in special circumstances), and X-rays are far beyond and not visible (and are harmful).
