electromagnetic waves with wavelengths shorter than visible light, but longer than X-rays
electromagnetic waves with wavelengths shorter than ultraviolet rays, but longer than gamma rays
reflection that occurs when parallel rays of light hit a smooth surface and all reflect at the same angle
reflection that occurs when parallel rays of light hit a rough surface and all reflect at different angles
