A) real and at infinity
B) virtual and at infinity
C) virtual and located between the object and lens
D) none of the above
Correct Answer: C
Solution :
In a concave lens, the maximum image distance for a real object can be equal to focal length. When the object is at infinity, the virtual image is formed at focus. When the object is anywhere between infinity and optical centre, the virtual image is formed between focus and optical centre. So, the correct option is [c]. Concave lens can form a real image of the object at infinity if the object is virtual and is at focus as shown in figure.You need to login to perform this action.
