Can you suggest a way for accurately measuring the focal length of a diverging lens without using a remote object and without using the parallax method to locate a virtual image? you may assume that simple devices like converging lenses, light sources, screens, plane mirrors are available.

Answer:
A way for accurately measuring the focal length of a diverging lens without using a remote a remote object and without using a parallax method to locate a virtual image is by simply projecting a real image of the object on a screen, and then recording the distance between lens and the screen.
Moreover, a diverging lens is being put in between converging lens and the screen. This way, the image will move back and we will be able to project the real image on the screen. Also, the initial position of the screen will be the place where the virtual image is going to form.

A diverging lens with a focal length of -3.5cm is 15cm from a 2.5cm-tall small lightbulb. A. Predict the location and height of the resulting image. Is it real or virtual? inverted or upright? B. Now a converging lens with focal length of 3cm is placed halfway between the diverging lens and the light. Predict the location, whether it is real or virtual, and the height produced by the combined lenses. C. Draw a ray diagram for the combination in...
