Answer:
It is real, inverted, and smaller than the object.
Explanation:
Let's start by using the lens equation to find the location of the image:
where we have:
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, we find
The sign of q is positive, so the image is real.
Now let's also write the magnification equation:
where
are the size of the image and of the object
By substituting p = 50 cm and q = 21.3 cm, we find
So we notice that:
: this means that the image is smaller than the object
: this means that the image is inverted
so, the correct option is:
It is real, inverted, and smaller than the object.
Hey there,
Your question states: <span>How long does it take for light from a star that is 8 light-years away to reach earth?
It take just about (</span>8 earth years) <span> for light from a star that is 8 light-years away to reach earth. That is how </span>
it would take.
Hope this helps.
