Yes, there is light we cannot see and x-rays and gamma rays are both examples.
Visible light is only a small portion of the wavelengths in the electromagnetic spectrum. Specifically, the visible wavelengths are 390 to 700 nm. Gamma rays, x-rays, and ultraviolet rays are all smaller wavelengths than visible light. Infrared, microwave, and radio waves are examples of wavelengths larger than visible light.
Some animals are capable of seeing Ultraviolet light, but humans are not!
