Waves are characterized by their wavelength. The wavelength is the distance between successive peaks or troughs of a wave. In the case of water waves, we simply find the highest part of the wave and then wait until the next high part comes by. This distance is the wavelength (Fig. 1). For electromagnetic waves, we can’t see the peaks and troughs, but sensitive instruments can detect them as they move by the detector. 1—Wavelength Typical water waves, like those on a lake, have wavelengths of 1 to 100 feet (ft).
Most were business transactions, just like our paper records today. These early tablets indicate that the Babylonians and Sumerians had begun to name some groups of stars, or constellations. A constellation is a group of stars in the sky, usually identified by a mythological creature or character. Some of the ancient Mesopotamian definitions are still in use today, such as Leo, Taurus, Scorpio, Ursa Major, Gemini, Capricorn, and Sagittarius. They also had begun to track the motions of objects in the sky, eventually developing a calendar based on these motions.
Imagine trying to push a Volkswagen Beetle that is sitting at rest and compare it with trying to push a cement truck at rest. Which is harder to push? The cement truck, of course: it is bigger and made of more matter and, therefore, has a larger mass. Newton’s third law describes how forces interact: for each action, there is an equal and opposite reaction. Forces act in opposition. Earth may tug on the Moon, keeping it in orbit, but the Moon also exerts a tug on Earth and they both rotate about a center of mass, a kind of balancing point located somewhere between the two objects.
