Question

If focal length is positive is the lens is a converging or diverging lens?

Answer 1

Answer:

In actuality, there are two focal points for every lens, the same distance from the lens, on opposite sides. The distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths.

Answer 2

Answer:

converging lens because it is convex lens and focal length of convex lens is positive
