प्रश्न
Two plane mirrors are placed making an angle θ° in between them. For an object placed in between the mirrors, if angle is gradually increased from 0° to 180°, how will the number of images change : increase, decrease or remain unchanged?
उत्तर
The number of images formed is given as n = `360/θ`
So, if q is gradually increased, n decreases.
