दोन समतल आरशामध्ये एक मांजर बसली आहे, जर दोन समतल आरशामधील कोन 30 अंश असल्यास, मांजरीच्या किती प्रतिमा दिसतील ? A cat is sitting in between two plane mirrors. If the angle between two plane mirrors is 30 degrees, how many images of the cat will appear?
1)0
2)1
3)11✓ Correct
4)12
Number of images formed by two inclined mirrors is given by formula (360/theta). Here 360/30 = 12. Since 12 is even, the number of images is (12 - 1) = 11.
