    @AvengerVirus The figure you have dra|dw:1351708439753:dw|wn. If an object is kept between the two mirrors. Infinite no. of images will be formed.

    I think the two mirrors are on the same wall, otherwise we'd have infinite no. of images. Figure should be like this|dw:1351708694076:dw| M1,2 ,3 are the mirrors.

    M1 and M3 have an angle of 90, how many images form if mirrors have an angle of 90?

    M1 and M2 are on the same wall. There won't be any secondary images between them. Just primary images.

    there is formula say 360/n-1 where n is the angle but it calculate the image that comes out of two mirrors is there any one for three mirrors ?

    it should be 12 but due to imposition of one image it will be 12-1=11

    use the same formula for the pair of mirrors and then there will be total of 12 with one image imposed by all three, like the mirror on ceiling with one mirror at 90 degrees will give four images, similarly with other it will give 4 and the two mirror adjacent to each other will give 4 total of 12 but one less

  39. AvengerVirus

    but the formula say 360/90-1 and that equal 3 why u say 4

    it is total of 9 images and two of them are imposed on each other so i am sure it's 7 , up to my knowledge

    is there a possibility that the other 2 image won't be imposed on each other ?

    yes there is if they are not placed at right angle to each other

  44. AvengerVirus

    so if the angle wasn't 90 we will calculate all the image like 60 360/60-1 = 5 then it will be 15 and we won't say any image is imposed to other right ?

  45. ghazi

    there are certain angles at which imposition occurs like 30, 60 90 but if we talk about 33.45 there might not be an imposition , but still there is possibility

    @ghazi what about this explanation Images I1 and I2 are primary images formed by the two plane mirrors. Image I3 was found by reflecting image I2 across the extension of the top mirror. And image I4 was found by reflecting the image I1 across the side mirror.

    @ghazi i think now am 99.99% as let's say three images one on each mirror and three others one on each crease and the last one at the point where they all meet then they r 7 do u agree with that ??
