A virtual image is produced by a convex mirror.
00:03
The magnification of which is one -fourth, or i'm going to leave it as 0 .25, the size of the original.
00:12
And we're told the distance of the object is 32 centimeters in front of the mirror, so it's positive.
00:18
And the first thing we want to find is image distance.
00:21
So we can do that from the magnification equation, where magnification is equal to the negative image of the, excuse me, distance of the image divided by distance of the object.
00:31
Multiply both sides by distance of the object to get distance of the image by itself and that negative.
00:38
And so let's go ahead and plug that in.
00:40
So we have distance of the image is negative 0 .25, which is our magnification, or you could have left it as 1 4th times 32 centimeters.
00:51
And we get negative 8 centimeters.
00:54
And that's what we should expect.
00:55
If it's virtual, the distance is going to be negative because it is behind...
