... Using a ray box, determine the focal length of the lens. Verify the focal length using another method. Place the candle at these locations: i) 3x the focal length in front of the lens ii) 2x the focal length in front of the lens iii) 1.5x the focal length in front of the lens Record the image charac ...

... Interference effects and diffraction result in “ringing” and spreading outside the aperture. Edges of image rise gradually (not abrupt) from zero. Intensity of image oscillates about the expected intensity. Oscillations decay as one approaches the center of the image. The oscillations are due to con ...

... A virtual object is one from which light rays appear to emanate but physically do not. A virtual image is one in which light rays do not physically intersect at the image point but appear to diverge from that point. Real images may be displayed on a screen while virtual images may not. All optical e ...

OPTICAL BENCH SET using METER STICK
... Set up the optical bench with a light source, object marker, a lens of 15 cm focal length, and screen as shown in photo. Place the object maker on the meter stick using the required distance. Place the light source at the end of the bench, the object marker about 10 cm from the light source, and the ...

Depth of field
In optics, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.
