Are you sure? Where is the image if the object is very near to the focal point in case of a converging lens?annalian said:Homework Statement
A punctual source of light is in the focal point of a diverging lens. in which distance from the lens is the image. Draw the road of rays.
Homework Equations
The objects at focal point don't have an image.
The formula for calculating image distance is 1/f = 1/o + 1/i, where f is the focal length of the lens, o is the object distance, and i is the image distance.
The distance of the object from the lens is directly proportional to the image distance. This means that as the object distance increases, the image distance also increases. Similarly, as the object distance decreases, the image distance decreases as well.
The focal length and image distance have an inverse relationship. This means that as the focal length increases, the image distance decreases, and vice versa.
Yes, the image distance can be negative. A negative image distance means that the image is formed on the same side of the lens as the object. This occurs in cases of virtual images, where the light rays do not actually converge to form an image.
The type of lens can affect the image distance by changing the focal length and the curvature of the lens. A convex lens will have a shorter focal length and a larger curvature, resulting in a shorter image distance. A concave lens, on the other hand, will have a longer focal length and a flatter curvature, resulting in a longer image distance.
