What is a wavelength?
Wave length The distance between the recurring units of the wool is measured from one point on the wave to the corresponding point in the next unit. For example, the distance from the summit - called the ridge - one wave unit to the other ridge is one wavelength. In the physics of notation, the wavelength is often marked with a Greek letter Lambda. The wavelength is inversely proportional to the frequency of the wool. In other words, the shorter the wavelength, the more wave units will pass at the time.
The wave is simply energy that moves through the medium. In addition to the context of physics, ocean waves are an excellent example of how the waves work. Except when the wave breaks, it is not the water that moves, because it is energy in the water that produces movement up and down that is evident near the coast. Physicists study waves of light and sound, as well as waves of other types of energy, and in this context, the wavelength is to define and consider the important factor.
Light waves are present all around us, to a very large range of wavelengths. This range is known as an electromagnetic spectrum whose small part is perceived by our eyes as visible light. In fact, the light of the Sun consists of the entire electromagnetic spectrum. Whether the type of light is visible to us depends on its wavelength. If a light wave has a wavelength between 400 and 700 nanometers, it will be visible to the human eye.
on both sides of this range are still short and increasingly long wavelengths. X -rays have wavelengths that are so short that they can pass by fixed objects. On the other hand, some radio waves have a wavelength of 1 mile (1.6 km) or more.
The sound is another form of energy that travels in the waves. Sound waves are similar to light waves, at least two ways: as perceived at wavelength and there are many wavelengths that are too short or too long to to to perceive. The difference is that we usually define the sound in terms of wave frequency rather than wavelengths, but these two are closely related, as already mentioned. The long wavelength sound wave will have a low frequency and we will hear these waves as low -resolution sounds. High sounds come from waves with short wavelengths and thus with high frequency.
