Unfortunately, the 3-foot mirror can be mounted in the perfect position for Amit to view his entire image. His sister who is 4 feet tall, may only need 2 feet of mirror to view her image. Yet the two foot section which her sister needs extends to positions on the wall below the 3 foot section which Amit needs. His sister's eyeball position is lower and thus she must sight at a lower position on the mirror in order to view her feet.
