A periscope (see figure below) is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches or parades from behind a crowd of people. Suppose the object is a distance p1 from the upper mirror and the centers of the two flat mirrors are separated by a distance h. What is the distance of the final image from the lower mirror? (Use any variable or symbol stated above as necessary.) d = ______ behind the lower mirror What is its magnification?

00:03 So in the question we have to give a periscope that is used for being objects that can always be added.

00:12 Okay, so what we have to do and to find the distance of the final image from the vulnerable.

00:22 We have to order and data and it is to the distance edge from each other and we have to find the distance and of the image which is found at the main level.

00:37 So first of all, the question we have to be able to have.

00:41 So there are two ladies.

01:01 Because you know that we have two flat mirrors and each flat mirrors have radius of condition to infinity.

01:10 Okay.

01:10 That means the coconut we close to infinity because the coconut is our radius, okay? so f maybe also in the okay then the upper mirror here, the upper mirror upper mirror and actual size image because it is a plain mirror so it will produce actual size image and also virtual image okay so according to this what we happen here one by you you that means position of the object and a position of holding okay, 1 by u, this will be equal to middle formula.

02:12 Okay, so 1 by u plus 1 by b is equal to 1 by x.

02:15 So 1 by u plus 1 type given plus 1 type given and we know that 1 by and 5 is 1 by infinity so this would be equal to 0.

02:25 That means komiya we can see that p21 equal to and pure 1.

02:31 Okay, the goodness of q1a.

02:33 Okay, now it will recall to the magnification, tagnification is equal to 1.

02:38 Magnification which is called to minus 2.

02:44 P1 over 2m.

02:46 Okay...
