A guy named Joe, who is 1.6 meters tall, enters a room in which someone has placed a large convex mirror with radius of curvature R equal to 30 meters. The mirror has been cut in half, so that the axis of the mirror is at ground level. (Figure 1) As Joe enters the room, he is 5 meters in front of the mirror, but he is looking the other way, so he fails to see it. When he turns around, he is startled by his own image in the mirror.
part A
How far away does the image appear to Joe?
Express your answer in meters, to three significant figures or as a fraction.
Part B
What is the image height yim that Joe sees in the mirror?
Express your answer in meters, to three significant figures or as a fraction.
Part C
Now what is the length (i.e., the distance from head to toe) of Joe's image?
Express your answer in meters, to three significant figures or as a fraction.

Joe is hiking through the woods when he decides to stop and take in
the view. He is particularly interested in three objects: a
squirrel sitting on a rock next to him, a tree a few meters away,
and a distant mountain. As Joe is taking in the view, he thinks
back to what he learned in his physics class about how the human
eye works.

A standard 14.16-inch (0.360-meter) computer monitor is 1024 pixels wide and 768 pixels tall. Each pixel is a square approximately 281 micrometers on each side. Up close, you can see the individual pixels, but from a distance they appear to blend together and form the image on the screen. Part A If the maximum distance between the screen and your eyes at which you can just barely resolve two adjacent pixels is 1.30 meters, what is the effective diameter d...

Learning Goal: To become familiar with using the image of one instrument as the object of the next and tracing rays through a system of multiple instruments. Multiple optics refers to any system of more than one optical instrument through which light passes. Most devices related to optics, such as cameras, microscopes, and telescopes, contain multiple optics systems. In multiple optics, the image of one optical instrument becomes the object of the next one. Thus, in multiple optics problems, you...

SOLUTION SET UP The center of curvature of the first surface of the lens is on the outgoing side, so R = +6.0 mm. The center of curvature for the second surface is not on the outgoing side, so R2-_5.5 mn. We solve for f and then use the result in the thin-lens equation. Now we'll apply the thin-lens equation to the eye When light enters your eye, most of the focusing happens at the interface between the air and...
