Question

Which one of the following statements concerning the image formed by a concave spherical mirror is true?

Question 11 options:

1) When the object distance is less than the focal length, the image is inverted relative to the object. 2) When the object is at the center of curvature, the image is formed at infinity. 3) When the object distance is larger than the focal length, the image is upright relative to the object. 4) When the object distance is larger than the focal length, the image is virtual. 5) When the object distance is less than the focal length, the image is virtual.

Explanation / Answer

Here ,

for a concave spherical mirror

1)    When the object distance is less than the focal length, the image is inverted relative to the object.

False ,the image is virtual and inverted.
   
2)    When the object is at the center of curvature, the image is formed at infinity.

false , the image is formed at the center of curvature.
   
3)    When the object distance is larger than the focal length, the image is upright relative to the object.

False , the image is real and inverted.
   
4)    When the object distance is larger than the focal length, the image is virtual.

false , the image is real
   
5)    When the object distance is less than the focal length, the image is virtual.

True , the image is virtual and up right

hence , the correct option is

5)    When the object distance is less than the focal length, the image is virtual.
