Physics Ripple Tank
If someone were to spend time near an ocean in the southern United States, they would probably notice one thing. They would notice that it was so hot, that they would need to cool off all day long. And the best way to do this would be to go to the nearest beach, and cool off in the refreshing waters. At the beach, they would hear the seagulls cawing, feel the hot sun shining down onto them, and they would notice all of the waves in the ocean. They may notice different wave phenomena, such as the waves breaking and growing and wonder what were going on, and why this phenomenon was occurring. Well, the answers to that person's questions, and more, will appear in this report.
The way we will answer these questions will be answered by looking at a ripple tank, designed to simulate the waves that occur throughout our environment. The first thing that will be looked at is to find the velocity of a wave in the ripple tank. The first way that we will find the velocity of the waves is that we will use the formula:
F = frequency
V = F (lambda)
When: lambda = area/waves in the area
But finding the frequency is a whole problem in itself. To find the frequency, we found that we could use an instrument that would turn over our eyes that would make the waves appear to stop. This is because the instrument would be turning at the same rate that the waves were moving. We could count the number of revolutions that were made in twenty seconds, and divide the two numbers and come up with the frequency part of our formula. (36 revolutions were made in 20 seconds, to give us a frequency of 1.8). To find the lambda part of the problem, we simply sectioned off an area, and counted the number of waves in that area using the device used in the frequency part of the problem. (12 waves were in an are .5 meters, making lambda= .5/12). Now, we simply plug in the values into the base formula, and we get our velocity at .45 meters/second.
To find the velocity a second way, we can use the formula: V = Distance/time.
Using this formula, we simply measured out a space, and counted how long it took a wave to go from one point to another point in a particular amount of time.
In this section of the book, "Wave", we are introduced to Sam and his family who are off to Thailand for their Christmas vacation. This is the first year that Sam's older sister Beth isn't able to go, this makes his mother upset and leads to an almost constant worry for her daughter. After parting ways with Beth and enjoying their time at the resort, riding elephants and sitting on the beach, Sam and his father notice that the ocean level had dropped out of nowhere; it happened so fast, that the fish couldn't even keep up with the receding tide. People were amazed by what was happening and all gathered by the beach but when the water starts to come back in, Sam and his parents find themselves retreating

We had to do measure the wave angle because it would show us in which
A seismograph station is located 2000 km from an earthquake’s epicenter. Explain the order that the S and P waves will arrive at the station by using the characteristics of the waves.
Wire time (or panghantar such as an antenna) conducts alternating current, electromagnetic radiation is propagated at the same frequency as the electric current. Depending on the situation, electromagnetic waves can be waves or like particles. As a wave, characterized by speed (speed of light), wavelength, and frequency. When considered as particles, they are known as photons, and each has an energy associated with the frequency of the waveform shown by the Planck relationship E = Hν, where E is the photon energy, h is the Planck constant - 6.626 × 10 -34 J · s - and ν is the frequency of the
Math- Students will evaluate his or her journey and predict how long it will take to travel from one destination to another. This can be done in many formats at the teacher’s subjection.
The Sun’s radiation heats the upper atmosphere, sending the energy toward the earth’s surface and finally mixes with the planet’s counter-rotational currents, creating jetstream flows. The winds flow over the ocean’s surface creating friction that spawns chops, pushing up the seas forming perfect bands of open ocean swell. Pushed on by gravitational forces, the swells speed away from the winds that they came from, moving across the deeps until they feel the drag of the shallows near the coast. As the swells rise up out of themselves, they peak, curling into the liquid dreams that we surfers ride (Kampton 4).
...n. When a sting ray swims past you or a jelly fish is there in the water beside you, again there is a realization of just how much is going on under the water that is not seen. The waves can make you feel so insignificant when you get tumbled head over heels in the water and you have no control over yourself. Only after experiencing this can the powerfulness of the waves be realized.
Speed(s) is the distance travelled divided by the total time it took to get from the starting point to the ending point, or:
moving back and forth in the same direction as the waves are traveling, as secondary or transverse shear waves, known as S
As previously stated, sound waves can travel through various mediums. The universal formula to obtain the speed of a sound wave is:Speed=distance/time.

Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclicalphenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies.[2] It is also the foundation of the practical art of surveying.
