Question
In the figure below is shown a small object (represented by an arrow) in front of a curved mirror. At the tip of the arrow is a red dot. The arrow is 1 cm long. The mirror is a piece of a sphere. The center of the sphere is marked in the picture with an x. The triangular objects are the eyes corresponding to three different observers.
A. How many red dots will the observer at position A see?
None, 1, 2, or More than 2
If one of the dots seen by observer A is an image dot, specify quantitatively how far from the mirror the dots will appear to be and how far off the axis they will be. (Take positive to be to the left and up on the left side of the mirror.)
Distance from the mirror =_______ cm
Distance from the axis =______ cm
B. How many red dots will the observer at position B see?
N=______ None, 1, 2, or More than 2
C. How many red dots will the observer at position C see?
N =______ None, 1, 2, or More than 2
Explanation / Answer
only 1 dot is appear for observer A because only a single image is formed
Distance from the mirror =_2.00 cm
there is no dot seen from position B because this point is the back of mirror
there is no dot seen from position C because this point is the back of mirror
