Newly discovered tombs that date back 4,000 years have revealed that paid labourers, not slaves, built the Great Pyramids of Giza. Hawass told reporters at the site that the find, first announced on Sunday, sheds more light on the lifestyle and origins of the pyramid builders.
A wavelength is the distance in between the repeating units of a wave, as measured from one point on a wave to the corresponding point in the next unit. For example, the distance from the top -- called the crest -- of one wave unit to the crest of the next is one wavelength.avelength is inversely proportional to the frequency of a wave. In other words, the shorter the wavelength is, the more wave units will pass in a given amount of time. A wave is simply energy that moves through a medium. Outside of the context of physics, ocean waves are an excellent example of how waves work.

Wavelength is the distance from one crest or trough to the next. Frequency is the number of waves passing a fixed point in a certain amount of time.
