Light waves that are of slightly higher frequency than you can see.
You may experience sunburned skin if you allow your skin to be exposed to the ultraviolet waves that penetrate the clouds on a cloudy day. Ultraviolet waves are at the opposite end of the visible light spectrum from infrared waves. Ultraviolet (UV) waves are longer than X-rays.
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.
Light waves usually refers to visible light but can also include infra red and ultraviolet light.
Ultraviolet light, visible light, X-rays, microwaves, radio waves, infrared waves, and gamma rays are all on the spectrum of light, are all electromagnetic waves (EM waves). Any EM wave can be considered light. EM waves are composed of photons, which has properties of both a particle and a wave. The difference between different waves on the EM wave/light spectrum is their frequency. For example, radio waves have a very low frequency, microwaves have a slightly higher frequency, then infrared, visible light, ultraviolet, X-rays, gamma rays, etc.
Ultraviolet waves are smaller than light waves.
Ultraviolet rays or infared rays
a torch that emits ultra-violet light
Starting at ultraviolet, longer waves are waves of visible violet light, and shorter waves are X-rays.
Ultraviolet is higher frequency, then visible light, then infrared.

ultraviolet light
Some insects use ultraviolet waves to find nectar. The ultraviolet light leaves marks on flowers, and the insects can sense them and find the nearby nectar.
You may experience sunburned skin if you allow your skin to be exposed to the ultraviolet waves that penetrate the clouds on a cloudy day. Ultraviolet waves are at the opposite end of the visible light spectrum from infrared waves. Ultraviolet (UV) waves are longer than X-rays.
Ultraviolet and visible light waves all travel at the same speed whenever they're all traveling through the same material.
Electromagnetic waves found in sunlight are light waves, ultraviolet waves and cosmic waves.
