Ultraviolet light, X-rays, and gamma rays do.
Shorter wavelengths.
Ultraviolet (UV) light has higher frequency and shorter wavelengths than visible light. UV light is invisible to the human eye but can be harmful in large doses, causing skin damage and increasing the risk of cancer.
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.
Wavelength, or alternatively its frequency.
As visible light moves from red to violet, its wavelength decreases and its frequency increases. This causes the color to change from longer, lower-energy wavelengths (red) to shorter, higher-energy wavelengths (violet). Red light has a longer wavelength and lower frequency, while violet light has a shorter wavelength and higher frequency.
Ultraviolet waves have shorter wavelengths than visible light.
Ultraviolet (UV) waves are on the higher frequency side of the visible spectrum, while infrared (IR) waves are on the lower frequency side. UV waves have shorter wavelengths and higher energy than visible light, while IR waves have longer wavelengths and lower energy.
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.
"shorter"
No, ultraviolet light has a shorter wavelength than visible light. Visible light falls within the electromagnetic spectrum with wavelengths ranging from approximately 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.
Ultraviolet rays have shorter wavelengths than infrared rays. Ultraviolet rays have wavelengths shorter than visible light, making them invisible to the human eye, while infrared rays have longer wavelengths.
That depends what you call "high" or "low". The frequency of ultraviolet waves is higher than that of visible light; lower than that of x-rays.
