Figure 3.2 Ray Tracing
➁ What is the perpendicular distance from the filament to the plane of the mirror (distance d
1
, as shown in the
Figure 3.2)? ________________________________________________.
➂ What is the perpendicular distance from the image of the filament to the plane of the mirror (distance d
2
, as
shown in the Figure)? _________________________________________.
Change the position of the mirror and the Light Source and repeat the experiment.
➃ What is the relationship between object and image location for reflection in a plane mirror?
________________________________________________________________________.
Additional Questions
➀ If one wall of a room consists of a large, flat mirror, how much larger does the room appear to be than it
actually is?
➁ Make a diagram illustrating why an image of the letter F, reflected from a plane mirror, is inverted. (Treat
each corner on the F as a source of light. Locate the image for each source to construct the image of the F.)
➂ How does the size of the image reflected from a plane mirror relate to the size of the object?
