Vedclass · Answer

(C) For a spherical mirror,the mirror formula is $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$.At point $P$,the graph intersects the line $v = u$,which implies $u = v$. Substituting this into the mirror formula: $\frac{1}{u} + \frac{1}{u} = \frac{1}{f} \implies \frac{2}{u} = \frac{1}{f} \implies u = 2f$. Thus,at point $P$,$u = v = 2f$.For points on the curve above $P$,the value of $v$ is greater than the value of $v$ at $P$. Since $v_P = 2f$,any point above $P$ on the curve corresponds to $v > 2f$.

The graph shows the variation of $v$ with change in $u$ for a mirror. Points plotted above the point $P$ on the curve are for values of $v$:
