Physics Question on Ray optics and optical instruments
The image formed by a concave mirror
A
is always real
B
is always virtual
C
is certainly real if the object is virtual
D
is certainly virtual
Answer
is certainly real if the object is virtual
Explanation
Solution
The image formed by a concave mirror is always real when the object is placed between focal point and infinity. But when the object is placed between focal point and pole, then the image is always virtual But when the object is virtual ie, object is placed far away from the focal point, then the image is certainly real Hence, the required answer is certainly real if the object is virtual
