... mountains makes them appear slightly blue and with less sharp contrasts. Overlapping layers with darker shadows in the foreground can add to the illusion by adding a motion parallax. Forced perspective seems to work well for small to moderate changes of perceived scale. A well-known object (like a roller...

...-PS4-5). Purpose The goals of this laboratory activity are to: Learn to locate images by the methods of parallax and direct aim, Review the properties of the image seen when using a flat mirror, and Demonstrate the law(s) that describe the reflection of light from a flat mirror. Materials...

... of reflection. (15 points) Explain how parallax can be used to locate the position of an image.(10 points) Parallax is the apparent shifting of objects relative to each other when they are viewed from different angles. The greater the distance between the objects the greater is the parallax...

... viewing position (i.e., your head) and, if necessary, adjust the position of the test object so that it is in the position of the image regardless of your point of view. When the test object seems to be in the same position as the image regardless of your viewing angle, we say that there is no parallax...

... to the mirror as possible. Is the image now upside down or right-side up? You should see that you have a virtual image when the object is closer to the mirror than the principal focal point. Since you cannot locate a virtual image by using a screen test, you will need to use parallax or direct aim. Thus, you...

...2. How does the size of an image formed by the reflection of light from flat plexiglass compare to the size of the test object when you placed it behind the plexiglass surface so as to minimize parallax? The object and test object (i.e., image) are the same size. 3. How...

... of Reflection lie in the same plane) Properties of images using a plane mirror: Location of an image. Three procedures for locating an image: Parallax (see Activity 14) Direct aim Screen test (only works for real images) Orientation of image (inverted or right-side up) Size of image...

... as a screen Cardboard Two pins (one pin will act as an object, and the other will be used as a parallax test pin) Procedures Determine focal length of converging lens Use a meter stick, some clay, and a small screen to find the focal points and focal lengths of your lens. The method is similar...

... distance. Location of Virtual Image Using Parallax Procedures Now place the flashlight bulb as close to the mirror as possible. Is the image now upside down or right-side up? You should see that you have a virtual image when the object is closer to the mirror than the principal focal point. Since you...
