Passing a current through hydrogen gas causes a purplish glow, which passes light through a prism separating the different colors into a line emission spectrum.
Visible light is made up of different colours, which form a Rainbow. White light is composed of all the colours in this rainbow. Each of these colours has a different wavelengths, with red being the...
The acronym is ROY G BIV or White light is separated into its component colours: RED ORANGE YELLOW GREEN BLUE INDIGO VIOLETWhite light is polychromatic (consists of many colours). The prism...
It is due to the differing frequencies of colors of light.The different frequencies of light actually travel at different speeds,through a medium such as glass.When the light enters glass at an...
Photons with different frequencies have different speeds in a medium and therefore different angles of refraction. Purple photons which have the highest frequency (in the visible spectrum) also have...
