Question 1 Let s begin by recognizing the parallax effect with our own eyes To see the parallax effect try the following hold your thumbs out from your nose one at arm s length and one closer to your nose you can also hold 2 pencils as pictured As you alternate opening and closing each eye you should be able so see the position of your thumbs jump back and forth relative to objects in the background This is because the centers of your eyes are a few centimeters apart so that each eye has a slightly different point of view a A Nearer pencil pink The brain judges distances to objects by comparing the view from the left eye with the view from the right eye The two views of nearby cbjects differ more than views of distant objects B Farther pencil blue Left eye Right eye O Relative to the background objects is the observed shift in the position of your thumb greatest for the thumb closet to your nose or further away Right eye view Left eye view
