The diameter of the reflecting curved surface of a spherical mirror is called _______.
एक गोलाकार दर्पण की परावर्तक वक्र पृष्ठ के व्यास को __________ कहा जाता हैं।
Detailed Solution & Logic
Aperture/ एपर्चर
Explanation
In a spherical mirror, the aperture is defined as the diameter of the reflecting curved surface of the mirror.
Other terms explained:
-
Pole (P): The center point on the mirror’s surface.
-
Focal length (f): The distance between the pole and the focus (F).
-
Radius of curvature (R): The distance between the pole and the center of curvature (C).
Extra Facts
-
A larger aperture allows the mirror to collect more light and produce a brighter image.
-
In concave mirrors, a larger aperture can cause spherical aberration, where rays away from the principal axis do not converge exactly at the focus.
व्याख्या
गोलाकार दर्पण (Spherical mirror) में एपर्चर (Aperture) दर्पण की विलंबित (curved) परावर्तक सतह का व्यास होता है।
अन्य शब्दों की व्याख्या:
-
पोल (Pole, P): दर्पण की सतह का मध्य बिंदु।
-
फोकल लंबाई (Focal length, f): पोल और फोकस (F) के बीच की दूरी।
-
विकृति त्रिज्या (Radius of curvature, R): पोल और केंद्र C (center of curvature) के बीच की दूरी।
अतिरिक्त तथ्य
-
बड़ा एपर्चर दर्पण को अधिक प्रकाश इकट्ठा करने और उज्जवल छवि बनाने में मदद करता है।
-
अवतल दर्पण (Concave mirror) में बड़ा एपर्चर कभी-कभी स्फेरिकल एबरेशन (Spherical aberration) उत्पन्न कर सकता है, जिससे धुरी से दूर के किरणें ठीक फोकस पर नहीं मिलतीं।
