Question

Choose the incorrect statement

• A. Aconvex mirror can form a virtual image of a virtual object.
• B. Aconvex mirror can form a real image of a virtual object
• C. Aconcave mirror can form a virtual image of a virtual object
• D. Aconcave mirror can form a real image of a virtual object

Answer 1

Answer: (C)

Aconcave mirror can form a virtual image of a virtual object

Answer 2

For concave mirror,

u = +x

f = –f

= – –

v = = –$\left[ \frac { \mathrm { f } } { 1 + \frac { \mathrm { x } } { \mathrm { f } } } \right]$

v = –ve means real image for all values of x.
