their wavelengths (frequencies)
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
The difference is their wavelengths.
White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.

Gamma rays are of higher energy and much much shorter wavelength than visible light.
The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light! so, in summery the difference is frequency and wave length.
Ultraviolet light has a greater energy per photon.
Visible light.
Light rays are visible and have higher frequency compared to that of heat radiation Heat radiation is nothing but infra red which is not visible to human eyes. They have longer wavelength compared to that of visible light
White light is a mixture of colours, light from gaseous elements is of one colour, sometimes of just one wavelength (frequency)
