Vedclass · Answer

(B) The person is suffering from myopia (nearsightedness), as they cannot see distant objects clearly.To correct this, the lens must form a virtual image of an object at infinity $(u = -\infty)$ at the person's far point $(v = -100 \, cm = -1 \, m)$.Using the lens formula: $\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$.Substituting the values: $\frac{1}{f} = \frac{1}{-1} - \frac{1}{-\infty} = -1 - 0 = -1 \, m^{-1}$.The power of the lens $P$ is given by $P = \frac{1}{f(	ext{in meters})}$.Therefore, $P = -1 \, D$.

$A$ person cannot see an object clearly if it is placed beyond $100 \, cm$. Find the power of the lens required to see an object clearly at infinity.
