Question

Which of the following depth cues would explain why, when you re standing at the exact same distance, Mount Rainier appears closer on some days than on others?

A. Binocular disparity

B. Relative size

C. Perspective convergence

D. Atmospheric perspective

Answer 1

ANSWER D: Atmospheric perspective

Reason - Because this depth cue makes the objects appear pale and less clear depending upon the dispersal of blue light in the atmosphere. This dispersal level is not constant. Hence, on some days the object appears more clear while on some days it appears pale and distant. Due to atmospheric perspective, the object from the same location may appear closer when it is clearer and distinct while it may appear farther when viewed as a pale image. Therefore, when you are standing at the exact same distance, Mount Rainier appears closer on some days when it appears to be distinct and clear, than on other days when it is pale due to atmospheric perspective.
