The focus of a concave mirror is situated at a distance of 16 cm from its pole. At what distance will its center of curvature be from its pole?

किसी अवतल दर्पण का फोकस इसके ध्रुव से 16 सें.मी की दूरी पर स्थित है, तो इसका वक्रता केंद्र इसके ध्रुव से कितनी दूरी पर होगा?

A

8 cm

B

16 cm

C

32 cm

D

64 cm

Correct Answer: Option C

Explanation / व्याख्या:

The distance to the center of curvature (radius of curvature) is twice the focal length. So, 2 x 16 cm = 32 cm.

ध्रुव से वक्रता केंद्र की दूरी (वक्रता त्रिज्या) फोकस दूरी की दोगुनी होती है। इसलिए, 2 x 16 सेमी = 32 सेमी।
