اگر لینس کی طاقت 10 ہے اور اس میں 14000:23 کے تناسب کے ساتھ سنگل موڈ انڈیکس فائبر ہے، تو لینس کی فوکل لینتھ کتنی ہوگی؟
Explanation
To calculate the focal length of a lens, you can use the formula: P = 1/f
Given that the power of the lens is 10 diopters, we can rearrange the formula to solve for the focal length:
f= 1/p
f= 1/10
f= 0.1m
Since 1 meter = 100 cm, the focal length in centimeters is 0.1m × 100 cm/m= 10cm.
