spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature‚ and density of the medium

How and why do we age? Ageing is ’The process of growing old’ [1]. This is known information to almost everyone that as we age‚ we show more signs of ageing such as wrinkles or age-related diseases. However‚ the reasons for this is still not fully known and consolidated‚ which is why many theories about ageing exist and scientists are still currently researching this topic. This essay will cover well known theories and biological phenomena on the topic of ageing with critical evaluation in answering

have contributed to theories involving light. Of these‚ the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history‚ some physicists have argued that light behaves as a wave‚ such as Christiaan Huygens and others‚ such as Isaac Newton have proposed that light consists of particles (Wave-Particle Duality‚ March 2010). Today‚ as stated in the wave-particle duality‚ light is said to exhibit wave-like and particle-like properties. And still today‚ physicists

Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times per second‚ the larva was not able to complete a full wave. This became more evident as the light continued to flash in a shorter time interval as the number of waves decreased as the MRR increased

The Wave Lily got up at 10:00 am like she does every morning during the summer. Then she got ready to go to the beach and surf. When she got there she went out in the ocean. When she first got out she saw a great wave‚ it was not too big but not too small. She then rode it into shore. Everything was going great until the waves started getting rough. She paddled out it was a little hard because the waves kept getting stronger. Then she heard a surfer yell for help. Lily started to swim as fast

Katsushika Hokusai’s print entitled The Great Wave is a Japanese art during the period ukiyo-e which is a movement that depicts everyday life. There were many materials used in this piece. Including “Ink‚ Paper‚ Printing blocks‚ Prints‚ Relief prints‚ Wood blocks‚ Woodblock prints”(metmuseum). The print was created after the artists fame had died down. In his late seventies‚ to pass time. Hokusai printed different views of Mount Fuji. The Great Wave being one of 36 and the most known. Hokusai‚ born

the south for the winter. This is because of the climate change butterflies cannot sustain. This route is over 3‚000 miles one way‚ however the migration is a two-way process. Butterflies however‚ unlike birds or other migratory animals‚ only travel one way and their generations after must take the journey back. Though this process may seem as a natural reaction of butterflies‚ how does it happen‚ where do they go‚ and how do they travel? Why do butterflies migrate? Butterflies are naturally cold-blooded

REVIEW of The Wave by Morton Rhue This story‚ based on a true incident that occurred in a high school in California‚ demonstrates how easily a group can lose its freedom without even realising it. It all began when their history teacher‚ Mr. Ben Ross‚ let them watch a movie on how the Nazis in World War 2 tortured the people who opposed them. To give them a clearer picture‚ he decided to them in the situation itself. He then introduced an organisation‚ The Wave‚ and its motto‚ "Strength
