Yes
According to the website below, they are blue because blue is the closest wavelength of the visible spectrum to ultraviolet light, and insects are attracted to ultraviolet light.
Spiderwebs can reflect ultraviolet light, making them visible to insects and birds that can see in the ultraviolet spectrum. The ultraviolet light can also cause the spider silk to fluoresce, creating a distinctive blue-green color.
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
Actually, the part of the electromagnetic spectrum that we can see is called visible light, not ultraviolet light. Ultraviolet light is outside the visible spectrum and is not visible to the human eye.
The wavelengths of visible light are longer than ultraviolet wavelengths.
The three types of centered wavelengths of light are ultraviolet, visible, and infrared. Ultraviolet light has shorter wavelengths than visible light, while infrared light has longer wavelengths. The visible spectrum, where light is visible to the human eye, falls between ultraviolet and infrared wavelengths.
Fluorescent materials, phosphorescent materials, and objects containing fluorescent dyes or pigments can emit visible light when exposed to ultraviolet light. This phenomenon occurs as the ultraviolet light excites the molecules within these materials, causing them to re-emit visible light at a longer wavelength.
No, the visible part is called visible light. Ultraviolet is invisible to the human eye.
Yes, they are not.
Visible light. The higher the frequency, the shorter the wavelength.
Visible light and ultraviolet rays are forms of electromagnetic radiation (EM). So are infrared, microwave and others.
No, it does not.
