Warm-up The reasons for seasons have a lot to do with the angle at which the Sun’s rays hit Earth. To see why‚ select the PLATE tab on the Seasons: Why do we have them? Gizmo™. The image shows a solar panel (Plate M) facing the Sun. Check that the Axis angle is set to 0˚. 1. Click Fire to release 100 “rays” of sunlight. Look next to “Number of hits” below the plate. How many of these rays hit Plate M? 100 2. Click Reset. Change the Axis angle to 40˚‚ and click Fire. How many rays hit Plate M now

The human eye and a camera lens have a few things in common most notably that they both use a converging lens to receive and project images. But human eyes and camera lenses have many things that set them apart from each other. “Retina Provides Color • the image an eye perceives is projected from the cornea to the retina‚ which absorbs the image and projects it to the brain. A camera projects an image on to film where it is captured and saved as a black and white image. The retina contains millions

Cameras in video games: comparing play in CounterStrike and the Doctor Who Adventures. Eric Laurier (Edinburgh University) & Stuart Reeves (University of Nottingham) Abstract Players of both first- and third- person perspective video games deploy a repertoire of analyses of the courses of actions of others with and through the game’s optics (be they other players or computer-generated actors). Visual activities of ‘looking around’‚ ‘scrutinising’ and ‘inspecting’ and so on‚ are achieved via

to a high density medium the angle of refraction decreases. With all the test done the angles of incident and reflection stayed the same. This is because with light what angle it approaches at is the angle the light will reflect back at. Also the angle of refraction depended on what the angle of incident and refraction were‚refraction is a dependent variable being the reason why the other angles matter. The first test was how light moves through air to water. The angle of incident was always 30 to

this experiment is to determine if the angle of impact affects the diameter and depth of a crater. The hypothesis was correct‚ stating that if the angle of impact changes than the depth and diameter will change due to the amount of speed and force is being put in the marble (meteor)‚ and the most effective angle for the diameter is at a 20 degree angle‚ and for depth is at a 90 degree angle. The hypothesis turned out to be true because it all depends to the angle the meteor or in this case the marble

There is a convention in the video‚ film and television industries which assigns names and guidelines to common types of shots‚ framing and picture composition. The list below briefly describes the most common shot types (click the images for more details).

Shots are usually described in relation to a particular subject EWS (Extreme Wide Shot) The view is so far from the subject that

Human Anatomy and Physiology Jaws Case Resolution Template 1) This case study focuses on the “unity of form and function” as represented in the biomechanics of jaw anatomy. What is the relationship between the length of the sarcomere and the tension generated by a muscle? What is the relationship between the length or thickness of the whole muscle and the force produced by the bite? What is the relationship between the length of the mandible‚ height of the ramus‚ and the angle

show. Shots‚ in addition to lighting and angles‚ can provoke powerful reactions in the audience. Steven Spielberg is well known for his cinematographic style. One of the movies he is best known for is Jaws. Three of the many interesting shots were the shark’s point of view‚ the zolly‚ and the shots of Captain Quint preparing for the shark. All three instigate suspense and keep the audience on the edge of their seats. An interesting group of shots in Jaws are the shark’s point of view shots. These
