ABCD shows the walls of a room such that AD = BC = 10 m and AB = CD = 6 m. The wall BC has a full length plane mirror. A camera is placed at the mid-point of the wall AD. Now to take clear image of the point D, the camera should be focused at

ABCD, एक कमरे की दीवारों को इस प्रकार दर्शाता है कि AD = BC = 10 m तथा AB = CD = 6 m है। दीवार BC की सम्पूर्ण लम्बाई पर एक समतल दर्पण है। एक कैमरे को दीवार AD के मध्य-बिन्दु पर रखा जाता है। अब बिन्दु D का स्पष्ट प्रतिबिम्ब लेने के लिए, कैमरे को केन्द्रित किया जाना चाहिए
