MCQ
If lateral magnification is $-2$ for virtual object for a spherical mirror then
- AConvex mirror, Real image
- ✓Convex mirror, Virtual image
- CConcave mirror, Real image
- DConcave mirror, Virtual image
✓
Answer
Correct option: B.
Convex mirror, Virtual image
b
Sine magnification is $-2$ so virtual object have virtual image.
virtual object to virtual image then mirror is convex.
Sine magnification is $-2$ so virtual object have virtual image.
virtual object to virtual image then mirror is convex.
