Question
Visual angle refers to the angle that is formed by an object when it is imaged on our retina. The visual angle can be determined from the following relationship: tan(angle)- size of object /distance from observer, or angle tan (size / distance) (remember to set your calculator to degrees!) size angle distance As we will see in class and these exercises demonstrate, many properties of our form and depth perception depend on visual angle and how it changes with distance 1. Visual angle. If an object stays the same size, then the visual angle it forms must change as we move closer or farther from it. Calculate the visual angle (in degrees) for each of the following stimuli. (You should only need your calculator for a; try b, c, and d without it): a. A person whose height is 2 m, standing 100 m away (m-meters) b. The same person standing 200 m away. c. A child whose height is 1 m, viewed from 100 m d. The same child viewed from 50 m.Explanation / Answer
1a. 1.15 degrees
1b. 0.57 degrees
1c. 0.57 degrees
1d. 1.15 degrees
2a. 1.75 meters
2b. 57.29 centimetres
