The relation between focal length (f) and radius of curvature (R) of a spherical mirror is
Show Hint
Remember the formula \( f = \frac{R}{2} \) when dealing with spherical mirrors.
Updated On: May 9, 2025
- \( R = \frac{f}{2} \)
- \( f = \frac{R}{2} \)
- \( R = f \)
- \( R = \frac{f}{3} \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The relationship between the focal length \( f \) and the radius of curvature \( R \) for a spherical mirror is given by:
\[
f = \frac{R}{2}
\]
This formula is valid for both concave and convex spherical mirrors.

- In a double slit experiment, the two slits are 1.5 mm apart. The slits are illuminated by a mixture of lights of wavelengths of 600 nm and 400 nm, and the interference pattern is observed on a screen 1.5 m away from the slits. Find the minimum distance of the point from the central maximum at which bright fringes of the interference patterns of the two wavelengths coincide.
