Question of The Day22-04-2024

_________ is used in periscope. / पेरिस्कोप ____________ में प्रयोग किया जाता है।

Answer

Correct Answer : a ) Plane mirror / समतल दर्पण

Explanation :

A plane mirror is used in the periscope.

A periscope uses a plane mirror to facilitate the observation of objects not directly visible from the observer's current location.

Encased within an outer casing, the periscope consists of two plane mirrors aligned parallel to each other at a 45-degree angle.

Hence, (a) is the correct answer.

Read notes on Light, an important topic in Physics.

पेरिस्कोप में समतल दर्पण का प्रयोग किया जाता है।

एक पेरिस्कोप एक समतल दर्पण का उपयोग उन वस्तुओं के अवलोकन की सुविधा के लिए करता है जो पर्यवेक्षक के वर्तमान स्थान से सीधे दिखाई नहीं देती हैं।

एक बाहरी आवरण के भीतर बंद, पेरिस्कोप में दो समतल दर्पण होते हैं जो 45 डिग्री के कोण पर एक दूसरे के समानांतर संरेखित होते हैं।

अतः, (a) सही उत्तर है।
