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.
Radiation is invisible to the human eye because it has a wavelength that is outside the visible spectrum. This means that the energy emitted by radiation is not within the range that our eyes can detect, making it invisible to us.
Light can be invisible if its wavelength falls outside the visible spectrum that the human eye can detect. For example, ultraviolet and infrared light are invisible to the naked eye but can still interact with objects and be detected by specialized equipment.
Infrared rays have a longer wavelength than visible light, making them invisible to the naked eye. They are typically in the range of 700 nanometers (near-infrared) to 1 millimeter (far-infrared) in wavelength.
Red light has the longest wavelength in the visible light spectrum.
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
radio waves
Violet light has the shortest wavelength of the visible spectrum.
X-ray & infrared
Any wavelength shorter than roughly 400 nanometers, and any wavelength longer than roughly 700 nanometers, is invisible. That is, its presence is not detected by the human eye.
Infrared light has a wavelength just outside the visible red wavelength. This type of light is longer in wavelength than red light, making it invisible to the human eye but detectable by special cameras or sensors.
radiation
Radiation is invisible to the human eye because it has a wavelength that is outside the visible spectrum. This means that the energy emitted by radiation is not within the range that our eyes can detect, making it invisible to us.
Light can be invisible if its wavelength falls outside the visible spectrum that the human eye can detect. For example, ultraviolet and infrared light are invisible to the naked eye but can still interact with objects and be detected by specialized equipment.

Red light has the longest wavelength in the visible light spectrum.
