JEE MAIN - Physics (2021 - 24th February Morning Shift - No. 8)
The focal length f is related to the radius of curvature r of the spherical convex mirror by :
f = r
f = $$-$$ r
f = +$${{1 \over 2}}$$ r
f = $$-$$$${{1 \over 2}}$$ r
Vysvětlení
For convex mirror, the focal length (f) and radius of curvature (r) are related as $$f = + {r \over 2}$$.
