I believe that is TRUE. I apologize if that is wrong, but i hope I helped!
Answer:
50 cm
Explanation:
Given that
Focal length of the mirror, f = 25 cm
Distance of the image, u = ?
Distance of the object, v = 50 cm
The formula for the focal length of a convex mirror is given by the relation
1/f = 1/u + 1/v,
where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have
1/25 = 1/u + 1/50
1/u = 1/25 - 1/50
1/u = (2 - 1)/50
1/u = 1/50
u = 50 cm
So then, we can conclude that the size of the image is 50 cm
