Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
When waves approach the shore they will “touch bottom” at a depth equal to half of their wavelength; in other words, when the water depth equals the depth of the wave base (Figure 10.3. 1). At this point their behavior will begin to be influenced by the bottom.
One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides.
When deep-water waves move into shallow water, they change into breaking waves. When the energy of the waves touches the ocean floor, the water particles drag along the bottom and flatten their orbit (Fig. 4.18 B). Transitional waves occur when the water depth is less than one-half the wavelength (D < 1/2 L).
Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. Orbital motions of water molecules becomes increasingly elliptical, especially on the bottom.
A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other. A spring tide is a common historical term that has nothing to do with the season of spring.Feb 26, 2021
What Moon phase occurs when the Sun Earth and Moon form a right angle and the Moon is moving towards the Sun Group of answer choices? Neap tides occur when the Moon and Sun form a right angle with the Earth.Dec 3, 2021
Neap tides occur when the Moon and Sun form a right angle with the Earth. In contrast to spring tides, neap tides are the effect of tidal forces canceling each other.Apr 24, 2017

In the earth's crust, the P-waves travel at around 6.5 km/s while the
Standing waves are produced in a string that is 4.0 m long. If the waves are travelling at 125 cm/s and the distance between the first and the fifth nodes is 80.0 cm, find the frequency of the waves.
