An f/2.80 CCD camera has a 105-mm focal length lens and can focus on objects from...
A lens for a 35-mm camera has a focal length given by f = 50.5 mm . How close to the CCD sensor should the lens be placed to form a sharp image of an object that is 5.20 m away?
A 200 mm focal length lens can focus on objects if they are between 2m and infinity away. What is the range of distances the lens must be from the film/detector?
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.
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 camera with a lens diameter D = 3 mm and a focal length of f = 4.25 mm. Assume the wavelength of light is 500 nm and the sensor in the camera is 5 mm x 5 mm and that each pixel has a size of 2μm x 2μm. A) If a vertical meter stick is located 5m from the camera and the image of the meter stick is in focus, how far from the lens is the sensor?...
To focus a camera on objects at different distances, the converging lens is moved toward or away from the image sensor, so a sharp image always falls on the sensor. A camera with a telephoto lens (f = 440 mm) is to be focused on an object located first at a distance of 3.5 m and then at 50.0 m. Over what distance must the lens be movable?
To focus a camera on objects at different distances, the converging lens is moved toward or away from the image sensor, so a sharp image always falls on the sensor. A camera with a telephoto lens (f = 270 mm) is to be focused on an object located first at a distance of 3.5 m and then at 50.0 m. Over what distance must the lens be movable?
Question 5 2 pts A telephoto lens for 35-mm film camera has a focal length of 190 mm, its f-stops (f - number of lens) range from f/2.8 to f/22. What is the corresponding range of aperture diameter? ΟΟΟ The aperture diameter ranges from 8.6 mm to 68mm The aperture diameter ranges from 2.8 mm to 22 mm. The aperture diameter ranges from 0.045 mm to 0.35 mm. The aperture diameter ranges from 35 mm to 190 mm. Next →
Review Constants Part A An underwater camera has a lens of focal length 35.0 mm and a maximum aperture of f/2.80. The film it uses has an emulsion that is sensitive to light of frequency 6.10x1014 Hz . If the photographer takes a picture of an object 3.10 m in front of the camera with the lens wide open. What is the width of the smallest resolvable detail on the subject if the object is a fish underwater with the...
Suppose your 48-mm focal length camera lens is 54 mm away from the image sensor in the camera. How far away, in meters, is an object that is in focus? What is the object height, in meters, if its image is 1.75 cm high? h_o =
