But do you mean the point of intersection has the same distance between the light source A and the reflected mirror image point A'?

Homework Statement It turns out there is a relation between angle a and angle b. I can't figure it out, could someone give me a hint? There's a lightray that is bouncing from two mirrors (m1 and m2). The angle between those two mirrors is called a. The angle between the incoming lightray l1...

well, how to image that it gets reflected like 4,5,6 times?

I guess there suppose to be lines in other virtual boxes.

Homework Statement Finding lightpaths with given starting and ending points via one or more mirrors. In those kind of problems you try image someone pointing a laser with a very narrow beam at a certain direction to the mirror, so it will reach point B. For example: You are seeing a square...

I guess you are suggesting a line of 180 degrees? Do you refer to the normal line?

Homework Statement Above is the basic cell drawn with an object inside of it. You look in top view of the basic cell and the space around it filled with virtual cells. You can see the top view of a basic cell (the square [that is marked blue] formed by the four real mirrors with a...

You think this has an actual name? "When you make your own drawing for this, for best results, when you construct the rays, measure the angles as carefully as possible, and use a ruler or straightedge to draw the lines." Yes, I know that there are 2 angles that are the same the angle between...

Thanks. But What type of 'special position' is meant here?

Homework Statement Please note that this is an extension of this question here: https://www.physicsforums.com/showthread.php?p=4571995#post4571995**Questions** Mirrors A and B with the space between them, including the bird, are part of the real world. Those are all a part of a basic cell...

Also: how would you add "mirror image B' of mirror B to mirror A." if some parts are obscured??

@haruspex: "we do not have a plan view of the set-up. It could be that B is much closer to us than is the bird" <-- No, this would make it too complicated, simply expect that this is not the case, you can see the bird in the mirror if your x-position is at A or B and your Y-position is at a...

I know this, but A is a mirror! Of course there is reflection on a mirror! Have you actually read the question? And you suppose to see the bird in mirror A, as stated in the question.

a mirror reflection Homework Statement Create a set-up, as shown in the Figure, consisting of two mirror tiles (A and B) and a bird face, facing to the right . Make sure the two mirrors are perpendicular to the table and parallel to each other. The situation shown is a front view of the...

How many similarity proofs do you need? Do you to proof that all 4 triangles are similar? (A-mirror-M is similar to A'-mirror-M is similar to B-mirror-M is similar to B'-mirror-M) Or can you do it in less steps?
