Question

Arnav was making notes and he wrote down the following statements from his understanding of reflection from curved surfaces.

1. Concave mirrors can produce both real and virtual images depending on the position of the object.
2. Convex mirrors always produce real, inverted images regardless of the object’s position.
3. In both concave and convex mirrors, the image location can be determined using the mirror formula `1/f = 1/v + 1/u` where f is the focal length, v is the image distance, and u is the object distance.

Choose from the following the correct option that lists the correct statements about reflection from curved surfaces.

Options

• I and II

• I, II and III

• II and III

• I and III

Answer 1

I and III

Explanation:

Statements I and III are correct because a concave mirror can form both real and virtual images, and the mirror formula is applicable to both concave and convex mirrors using proper sign conventions.

Statement II is incorrect, as convex mirrors always form virtual, erect and diminished images.
