प्रश्न
A student wants to obtain an erect image of an object using a concave mirror of 10 cm focal length. What will be the distance of the object from mirror?
पर्याय
Less than 10 cm
10 cm
between 10 cm and 20 cm
more than 20 cm
उत्तर
Less than 10 cm
Explanation:
Only when the object is positioned between the pole and the focus can a concave mirror produce an upright image.
Distance between pole and focus = Focal length = 10 cm
As a result, the object can be placed less than 10 cm from the mirror. As a result, the image created when an object is put between the pole and the focus. The virtual, upright, and expanded concave mirror.
