Ultraviolet, X-ray, and gamma radiation do.
We know that ultra-violet light, X-rays and gamma rays have higher energy (higher frequency and shorter wavelengths) than visible light.
We know that ultraviolet light, X-rays and gamma rays have wavelengths shorter than visible light.
"shorter"
Ultraviolet light, X-rays, and gamma rays do.
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
Light energy with wavelengths longer than visible red is infrared light.
We know that ultraviolet light, X-rays and gamma rays have wavelengths shorter than visible light.
Shorter wavelengths means higher frequency, and electromagnetic waves with higher energy. Beyond the blue end of the visible light you have ultraviolet rays; X-rays; and gamma-rays, in that order.
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
There are an infinite number of wavelengths above visible, below visible, and within visible. Since reality has infinite resolution, we can imagine varying the wavelength with infinite division. To call out bands of wavelength: Ultraviolet, X-rays, & Gamma rays.
Infrared rays have a shorter wavelength than microwaves and radio waves. All are examples of electromagnetic radiation.
Ultraviolet and up have shorter wavelengths.
