infrared light:)
Electromagnetic waves can travel through a vacuum.
From the items on that list, infrared light has the lowest frequency, and X-rays have the highest.
Those are the light waves that are visible when the sun light is refracted through the rain drops in the sky.
A Light Year is a measure of distance. If a star is 61 light years away, then it would take light (or radio waves, which travel at the speed of light) 61 years to get there.

they are electromagnetic. So they have an electromagnetic spectrum.
Light waves are organized by R.O.Y.G.B.I.V. Which is the rainbow, red ,orange,yellow,green,blue,indgo,and vilolet. Also by wavelengths.
Electromagnetic waves can travel through a vacuum.
Wavelength
Distomat is an instrument used to measure distance using light and radio waves.
Between Yellow, Green and Violet, the Yellow color has the longest light wave. The order of the 7 rainow colors, sorted by their light waves from the longest to the shortest, is as follows: Red, Orange, Yellow, Green, Blue, Indigo and Violet.
they travel at a different frequency.
If its light from the sun, yes, its vast distance from us means the light waves are essentially parallel
Light waves are not like sound waves, they do not require any medium for the wave to move because they themselves are made up of particles called photons. The distance between two photons in a ray of light is called its wavelength.
Yes. Sound waves have different frequencies which cause them to be louder/softer/higher/lower.Light waves have different frequencies too. The shorter the distance between the wavelenghts the darker the color. White light (the normal light the sun gives) is all of the colors together
yes, it's between red and yellow waves on the electromagnetic spectrum.
