Answer:
Inverted
Explanation:
See attached picture for the ray diagram, where
P is the object location
F is the focal length
Q is the image location
Each tick corresponds to 10 cm, so
p = 40 cm
f = 20 cm
--> q = 40 cm, so the image is located at the same position as the object
We also see from the diagram that the image is inverted.
This can be verified also by using the mirror equation:
[tex]\frac{1}{q}=\frac{1}{f}-\frac{1}{p}=\frac{1}{20 cm}-\frac{1}{40 cm}=\frac{1}{40 cm}\\q = 40 cm[/tex]
and the magnification is
[tex]M=-\frac{q}{p}=-\frac{40 cm}{40 cm}=-1[/tex]
which means:
- image is inverted (because magnification is negative)
- Image is same size as the object (because |M| = 1)
