Answer: The point where the ray of light seems to refract and diverge is called as the principal focus, and the distance between the principal focus and center of the lens is called the focal length (which is negative in this type of lens) of the concave lens. ..

Answer:

For a diverging lens (for example a concave lens), the focal length is negative, and is the distance to the point from which a collimated beam appears to be diverging after passing through the lens.
