- . 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?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? show diagram with explanationOur eyes are typically 6 cm apart. Suppose you are somewhat unique, and yours are 3.50 cm apart. You see an object jump from side to side by 0.75 degree as you blink back and forth between your eyes. How far away is the object?
- Walking along the edge of a pool, you see a quarter resting on the bottom of the pool. The light reflecting off the quarter enters your eyes at a 37o angle below the horizontal. Is the quarter closer or farther away from you than it appears?(a) Does your bathroom mirror show you older or younger than you actually are? (b) Compute an order-of-magnitude estimate for the age difference based on data you specify.MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A mirror hangs 1.80 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.07 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall. (a) What is the change in the angle of elevation of the Sun, between the two observations?
