You wish to create an image that is 10 meters from an object. This image is to be inverted and half the height of the object. You wish to accomplish this using one spherical mirror.
Part A
What is the focal length of the mirror that would accomplish this?
Express your answer in meters, as a fraction or to three significant figures.
Part B
Is this a concave or convex mirror?
1.concave
2.convex
Part C
What is the magnitude r of the radius of curvature of this mirror? Express your answer in meters, as a fraction or to three significant figures.
Part D
What type of image is created, real or virtual?
a) real
b)virtual

Part A
As the image is inverted,the image is real and the spherical mirror must be concave.
The magnification ‘m’ is 0.5 = – v /u
v / u = 0.5 or v = u / 2
thus v and u have same sign, it means
Let object distance ‘u’ from mirror be ‘x’ meter
As image distance from the object is 10 meter
then image distance ‘v’ from the mirror is (10 + x)
But v= u / 2
therefore (10+x ) = (x/2)
x= – 20 m
Object is at 20 m from mirror and image is 10 m from mirror
The mirror formula 1/ f = 1/v + 1/u gives
1/f =1/(10) + 1 / (20)
1/f= 3 /20
Focal length of concave mirror is 20 /3 meter = 6.667 meter

Part B
Only concave mirrors form real inverted image smaller than the object.l
As the image is inverted,the image is real, It is a concave mirror
__________________________________________________________________
Part C
The radius of curvature is twice the focal length.
The radius of curvature is 40 /3=13.333 meter
________________________________________________________________
Part D
The image is inverted,( only concave mirrors form real inverted image smaller than the object) therefore the image is real

Ok, let’s remember :
1 / p + 1 / q = 1 / f
p = object distance
q = image distance
If the image is 10 meters from the object, then : p – q = 10
” I am considering that the image is in the same side as the object”
also, the image is inverted, and it’s half the height of the object, so then :
q / p = – 1/2
It’s minus 1/2, because it’s inverted, and half height of the object :
q = p /2
p – q = 10
then : p = 20 and q = 10
Then :
1 / 20 + 1 / 10 = 1 / f
20 / 3 = f
f = 6.223 cm >>>>> Focal lenght
The mirror, is a concave mirror
The image is real
Hope that helps

I dunno. I used to have something like that, but now my wife keeps them in a jar by the bed. I think the left one is worth about $200, which is why you hear guys say, “I’d give my left nut to have sex with that girl.” I think the right one contains your magical ability to make decisions. I don’t know for sure because I don’t have my right one on right now. Together, they distinguish you apart from Eunichs like me.
