A physicist is hired to do some decorating at a celebration. The client is very keen on including some lighting effects, and in particular wants to have 365 stripes of yellow light (581.0 nm) evenly distributed on a 5.00 m Plexiglas board.a) Draw a labelled sketch of the display installation using an air wedge.b) Calculate the number of pieces of paper (each 1/10th of a millimeter) the physicist would need to insert at one end of the boards to make this happen.
Just beneath the surface of some very placid water (n = 1.33), lurks a shark. A piece of meat is dangled above the water’s surface and at a considerable horizontal distance away from the shark, as shown above. You are having a discussion with your two friends about whether the shark will be able to see the meat. Friend 1 – says that the shark will not be able to see the meat. Friend 2 claims that the shark can see the meat, only the shark will perceive the meat to be higher than it is in reality. Which friend (if either) do you agree with?
Can you support your answer with a diagram?

- . You are some type of half fish half human thing. From underwater you see a bird flying above the surface. You want to hit it with your spear (reverse spear fishing), but you know that your aim will be off due to refraction. Where will you need to aim in order to correct for lights changing pathway? either draw a picture with a small description of what to do or provide a detailed description of what to do and why. (picture = 1000 words and all that) 2. An astronaut has found a transparent (although slightly reflective and a little bit foggy) gem floating in space. They shine a laser into the gem at about 30 degrees away from the normal line and see that inside of the gem the laser is refracting to 50 degrees away from the normal line. What is unusual about this gemstone?arrow_forwardWhat is the smallest thing we can see? O smallest object that we can process with our eyes is limited to the size of the photoreceptor cells in the retina. In order for us to to distinguish any detail in an object, its image cannot be smaller cannot be smaller than a single retinal cell. Although the size depends on the type of cell (cone or rod), a diameter of of a few microns (mm) is common near the center of the eye. We should model the eye as a sphere 2.50 cm in diameter with a single slender lens in front and the retina behind, with photoreceptor cells 5.0 mm in diameter. (a) What is the smallest object object that you can perceive at a point near 25 cm? What angle is subtended by this object in the eye? Express your answer in units of minutes (1° 60 min) and compare it with the typical experimental value of about 1.0 min. (Note: there are other limitations, but we will ignore them here).arrow_forwardReview Conceptual Example 4 as background for this problem. A man in a boat is looking straight down at a fish in the water (n = 1.333) directly beneath him. The fish is looking straight up at the man. They are equidistant from the air/water interface. To the man, the fish appears to be 2.1 m beneath his eyes. To the fish, how far above its eyes does the man appear to be? Number i Unitsarrow_forward

- Suppose a Cathode Ray Tube - CRT has scanning speed of 3cm/millisecond. There are two types of displays, one is a Vector Display and another a Raster Display. The size of both displays is same, 10cm x 10cm and both has the same CRT installed in them. An outline of a square, having each side of 6cm, has to be displayed on both the screens. If a solid square shape has to be displayed (not only outline, but a filled square shape) on both the displays, which display would be better? Explain your answer.arrow_forwardAn object is placed to the left of a concave lens with focal length -10 cm such that the image produced by the lens is exactly half the size of the object. In a neat and organized fashion, write out a solution which includes the following: A sketch of the physical situation with all given physical quantities clearly labeled. Draw a ray diagram showing the object, the lens, and the image. Determine the location of the object and the image. Clearly show all steps, starting from generalized equations. Explain your mathematical work in words. Your explanation should cover both what you did and the thought process behind why you did that.
