92.A beam of light from a source L is incident normally on a plane mirror fixed at a certain distance x from the source L. When the mirror is rotated through a small angle theta L, the spot of the light is found to move through a distance y on the scale. The angle theta is given by-- (1) x/2y (2) x/y (3) y/2x |
