Ray optics (a ray model for light) PHYS 222 Lab 7 homework Homework questions Use the observations you made with the pinhole camera and what you have learned about the way light behaves during lab to answer the following questions. 1. Choose one of the objects you observed. Explain in words what the image inside the camera looked like. 2. Use a ruler to draw a neat and detailed ray diagram to explain the image you observed. 3. If the pinhole were made slightly larger, what would you expect to see? What if it was made much larger? Slightly smaller? Much smaller? Explain your reasoning. 2Ray optics (a ray model for light) PHYS 222 Lab 7 homework Homework questions Use the observations you made with the pinhole camera and what you have learned about the way light behaves during lab to answer the following questions. 1.

Light from a scene passes through the aperture and projects an image on the opposite side of the box, which is known as the camera obscura effect. Written references to this camera obscura date as far back as - aperature 400 BC, when Chinese philosopher Mo-tzu (or Mozi) noted that (pinhole) light which passed through a pinhole into a dark room created an inverted image of the original object. viewing hole Observations After you have finished Lab 6 (ray optics), you will need to make some observations using the pinhole camera. Use this space to write down your observations using words and sketches. You will use your observations from lab to answer the questions for your post-lab homework. Your pinhole camera has two different apertures, one that is a simple pinhole and one that contains a lens. With your lab partners, go outside and aim the aperture towards the tree line. Put your eye up to the viewing hole. Slightly adjust where you aim the pinhole until you can see an image projected onto the back wall on the inside of the camera. Explore viewing a few different things with the camera. Note: You may want to use the lens to make observations inside the classroom. 1. What do you observe when you use the simple pinhole? Use words and a simple sketch. 2. What do you observe when you use the lens? Use words and a simple sketch.Lab 6: Homework Name: Background pinhole camera A pinhole camera is a simple camera without a lens but with made from a cardboard box a tiny aperture (pinhole)-effectively a light-proof box with a small hole in one side.

If you viewed this object with the pinhole camera what would you expect to see? Object: F Image: (a) 5. Draw two neat and detailed ray diagrams to support your answer to #3 (one side-view and one top-view). Your diagram should explain both the vertical and horizontal orientation of the image.Ray optics (a ray model for light) 4. Imagine that an "F was projected onto a wall.
