Answer:
It is real, inverted, and smaller than the object.
Explanation:
First of all, we can use the lens equation to find the location of the image:
where
q is the distance of the image from the lens
f = 15 cm is the focal length (positive for a converging lens)
p = 50 cm is the distance of the object from the lens
Solving the equation for q,
The distance of the image from the lens is positive, so we can already conclude that the image is real.
Now we can also write the magnification equation:
where are the size of the image and of the object, respectively.
Substituting p = 50 cm and q = 21.3 cm, we have
So from this relationship we observe that:
--> this means that the image is smaller than the object, and
--> this means that the image is inverted
so, the correct answer is
It is real, inverted, and smaller than the object.
