Question

Pushkar was studying a light phenomenon and wrote down the following statements in that context: (i) A concave mirror can be used as a shaving mirror because it can form an enlarged, virtual image when the object is placed between the pole and focus. (ii) A convex lens always forms real, inverted images, regardless of the position of the object. (iii) The relationship between object distance ( $u$ ), image distance ( $v$ ) and focal length ( $f$ ) of the lens is given by $\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$ .

Choose the option enlisting all the correct statements:

Accepted Answer

B. - Statement (i) is correct: concave mirrors form magnified virtual images when $u < f$. - Statement (ii) is false: convex lenses form virtual, erect images when the object is between $F_1$ and $O$. - Statement (iii) is correct: $\frac{1}{f} = \frac{1}{v} - \frac{1}{u}$ is the standard lens formula. Hence, statements (i) and (iii) are correct.
