Use the lens formula,
1/f = 1/v + 1/u
for u = infinity,
=> v = 0.2 m = 20 cm
for u = 2 m,
=> v = 0.2222 m = 22.22 cm.
So, the range of distance where the lens must be from the detector will be from 0.2 meters to 0.2222 meters.

An f/2.80 CCD camera has a 105-mm focal length lens and can focus on objects from infinity to as near as 30.0 cm from the lens. (a) Determine the camera's aperture diameter. Deter- mine the (b) minimum and (c) maximum distances from the CCD sensor over which the lens must be able to travel during focusing. Note: "f/2.80" means "an f-number of 2.80."

2. A camera has a single converging lens with a fixed focal length f. (a) How far should the lens be from the film in order to focus an object that is infinitely far away (namely the incoming light rays are parallel with the principal axis of the system) (b) How far should the lens be from the film to focus an object at a distance of 2f in front of the lens? (c) What is the magnification of the...
A 105 mm focal length lens is used to focus an image on the sensor of a camera. The maximum distance allowed between then lens and the sensor plane is 132 mm. How far in front of the sensor should the lens (assume thin) be positioned if the object to be photographed is place 7.5 m away. a. 105 mm 106.49 mm Ob. 106.11 mm Oc. 132 mm d.
The focal length of the lens of a simple film camera is 40.0 mm. By what amount should the distance between the lens and the film be increased or decreased to change the focus from a person who is 25 m from the lens to one who is 4.0 m from the lens? A) 0.3 mm B) 0.7 mm C) 0.2 mm D) 0.4 mm E) 0.5 mm Please show work. Thanks
