योग्य उत्तर 5 आहे.

संकल्पना:

  • जर एखाद्या वस्तूची प्रतिमा दोन समतल आरशांमध्ये पाहिली गेली असेल जे एकमेकांकडे झुकत असतील तर एकापेक्षा जास्त प्रतिमा तयार होतात.

प्रतिमांची संख्या दोन आरशांमधील कोनावर अवलंबून असते.

\({\rm{Number\;of\;images}} = \frac{{360}}{θ } - 1\)

उदाहरणार्थ :

जर θ = 60° तर n = 5. तर 5 प्रतिमा तयार होतील ज्या दिलेल्या आकृतीमध्ये पाहिल्या जाऊ शकतात.

1 optics

गणना:

दिले आहे की:

θ = 60° 

\({\rm{Number\;of\;images}} = \frac{{360}}{θ } - 1\)

प्रतिमांची संख्या (n) = (360/60) - 1 = 6 - 1 = 5

म्हणून पर्याय 3 योग्य आहे.
