When a clock when viewed in plane mirror and it shows 4:30, then the actual time in the clock is 7:30.
- The image formed by a plane mirror has the characteristics of erect, vertical and zero magnification.
- Also, the distance of the object from the mirror to the distance of the image from the mirror.
- So, as the image shows the minute hand to be in 30 mins mark, the actual clock would show the same.
- The hour hand however will be shifted by the same angle, so when it shows at 4 in the mirror, actullay it is at 7.
