Hello everyone.
00:01
So in a given situation you can read that object, okay? the object condition is given that is a u is considered a minus of a 10 centimeter in front of a lens, okay? and he says that is a magnification, okay, that is a three times.
00:19
So we can write here that is a magnification m can be represented by a v by u.
00:24
But in that case he says that is a real.
00:27
So for a real image, for a real image, you can see that this is a principal axis, so that is an object condition and that is an image condition for a real condition.
00:41
So in that case, this is a positive and negative.
00:44
So in a real condition, we can mention here v by u is equivalent to minus 3 because this is a three times more.
00:52
Now guys, we can also write here, this is the equation v by u...
