Wave length

A wavelength is the distance between the same locations on adjacent waves. As an example; an ocean full of waves, that were 10 meters apart, could be said as, having a wavelength of 10, whereas an ocean of waves that were 30 meters apart would be said as having a wavelength of 30. The same applies to light. The colour RED has a wavelength of around 700 nanometers long - one wave spans only 7 ten millionths of a meter! Whereas, Violet has a much shorter wavelength, so each violet wave would span a much shorter distance. Waves of Energy Within the Universe, positive and negative charges (waves of energy), are constantly vibrating and producing electromagnetic waves traveling at an incredibly high speed.(186,000 miles per second, the speed of light.) Each of these waves has a different wavelength and speed of vibration. Together they form the electromagnetic spectrum. Light travels in waves. A wavelength is the distance between the same locations on adjacent waves.
