Visible Light
Waves
Visible light waves are the only
electromagnetic waves we can see. We see
these waves as the colors of the
rainbow. Each color has a different
wavelength. Red has the longest
wavelength and violet has the shortest
wavelength. When all the waves are seen
together, they make white light.
When white light shines through a
prism, the white light is broken apart
into the colors of the visible light
spectrum. Water vapor in the atmosphere
can also break apart wavelengths
creating a rainbow.
Each color in a
rainbow corresponds to a different
wavelength of electromagnetic spectrum.
