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.
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
Ultraviolet (UV) waves have shorter wavelengths and higher frequencies than visible light waves. They are not visible to the human eye but can cause sunburn and skin damage. UV waves are also used in sterilization, fluorescence, and to detect counterfeit money.
The wavelength of invisible light can vary depending on the type of light. For example, infrared light has wavelengths longer than those of visible light, ranging from about 700 nanometers to 1 millimeter. Ultraviolet light, on the other hand, has wavelengths shorter than those of visible light, ranging from about 10 to 400 nanometers.

Two types of light that are not visible to the human eye are ultraviolet (UV) light and infrared (IR) light. Ultraviolet light has wavelengths shorter than visible light and is often associated with sunburns and fluorescent effects, while infrared light has longer wavelengths and is primarily associated with heat. Both types of light play important roles in various technologies and natural processes, despite being invisible to us.
If the lights from all visible wavelengths are combined, they appear to be a white color.
Ultraviolet light is also known as UV light. Ultraviolet light is electromagnetic radiation wavelengths and is emitted in black lights, tanning lamps and sunlight.
Fluorescent lights emit a spectrum of visible light that typically includes various wavelengths in the blue and green regions, with smaller amounts in the red and violet regions. They also emit ultraviolet light, which is not visible to the human eye but can cause fluorescence in certain materials.
Different wavelengths of light have different colors.
Ultraviolet (UV) refers to electromagnetic radiation with shorter wavelengths and higher energy than visible light. UV radiation is not visible to the human eye but is present in sunlight and commonly used in sterilization, tanning beds, and fluorescent lights. Excessive exposure to UV radiation can be harmful to living organisms, causing sunburn and increasing the risk of skin cancer.
The shorter the wavelength (blue rather than red), the higher the energy.
Ultraviolet light is invisible to the human eye. UV light is found in sunlight and is emitted by electric arcs and specialized lights such as black lights. It can cause chemical reactions, and causes many substances to glow or fluoresce. Most ultraviolet is classified as non-ionizing radiation.
