Sunlight contains a few different beams on the electromagnetic spectrum. The most noticeable is visible light. Since the light is white, it contains all of the colors on the visible light spectrum (from red to violet, 700nm-400nm). There is also ultraviolet rays (400 nm to 10 nm) which is invisible to the human eye but in certain doses will cause skin cancer. Since the sun emits heat that warms the earth, sunlight also emits infrared radiation (750 nm to 1 mm).
