When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…
loud voices. The blue salty ocean waves pushing against the sand and the wind whistling in your ear very loudly. Loud music playing from the giant black jukebox in the background.…
The Wave is all about types, and Robert Billings is no exception; he's the school loser, to use the novel's rather cruel terminology. Other students in the school are afraid to ruin their own image by hanging out with the “class creep”. Ben Ross thinks that part of his problem is living in the shadow of his ultra-popular brother, who used to attend Gordon High School. When the Wave finally comes along, Robert seizes the opportunity to make a change, but things get even worse. Although some might…
the time at the beach we were playing in the sand and the shallow water. Then I and my cousin Nic decided to ride the waves with tubes. I got a little to far out and my aunt called for me to come closer as I was swimming back I was facing shore as I was almost where my aunt wanted me my cousin Nic screamed: "Ciana look out". As he said look I turned around and about a fifteen-foot wave took me under the water. While I was under the water all the water got in my mouth and I was under for about…
matter, which is a solid, liquid or gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2. Can sound move through…

the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the left hand side of the equation represents the local rate of change of action density in time. The second and third…
sail boating, went swimming in the ocean, buggy board, sand volleyball, swam in the pool, walked the beach at night, got henna tattoos, a dread in our hair and went to the club with my brother and Emerson. The sand on my feet, the crashing of the waves, people swimming in the ocean, the smell of sunscreen and the wonderful taste of my flamingo drink; Mexico is my kind of place to be. But the first day in particular sticks out to me the most, the day we went parasailing and sail boating. Waking…
It was a hot summer day and a perfect day to go swimming. The river was flowing calmly to the south and the currents were just strong enough to make me drift along without any efforts. Little did I know that I was about to experience the worst nightmare of my life. We all go through life, day after day, without thinking much about our purpose. We take life for granted and we think we deserve to be alive until such a moment when we come so close to death and we are suddenly jolted to a…
The waves moved gently with the wind. Odysseus shouts some orders to his crew, while the sun beats down on his face. The smell of the water filled the nostrils of the crew, as they sailed for home. In The Odyssey and O Brother Where Art Thou, Odysseus and Everett went on long journeys to get back to their family. However, they did not embark on the journey alone, each had a crew that came with them. The crews were not extras in a Batman movie, they were huge parts of the journey that added to…
