In Fig. 34-26, stick figure O stands in front of a thin, symmetric lens that is mounted within the boxed region; the central axis through the lens is shown. The four stick figuresI1andI4suggest general locations and orientations for the images that might be produced by the lens. (The figures are only sketched in; neither their height nor their distance from the lens is drawn to scale.) (a) Which of the stick figures could not possibly represent images? Of the possible images, (b) which would be due to a converging lens, (c) which would be due to a diverging lens, (d) which would be virtual, and (e) which would involve negative magnification?

Short Answer

Expert verified

(a) The sick figures that could not possibly represent images areI2andI3.

(b) The sick figures that represent a converging lens areI1andI4.

(c) The sick figure that represents a diverging lens isI1.

(d) The sick figure that represents a virtual magnification isI1.

(e)The sick figure that represents a negative magnification is I4.

Step by step solution

01

Definition of a converging lens and diverging lens

The lens that allows the rays of light to focus on one point is termed a converging lens and the lens that allows the rays of light from one point to scatter at different points is termed a diverging lens.

02

(a) Determination of the sick figures that could not possibly represent images

The lens forms an image on the left of the lens as upright and on the right of the lens as inverted.

Thus, the sick figures that could not possibly represent images are I2andI3.

03

(b) Determination of the sick figures that represent a converging lens

The converging lens forms an image on the left of the lens as upright and on the right of the lens as inverted.

Thus, the sick figures that represent a converging lens are I1andI4.

04

(c) Determination of the sick figures that represent a diverging lens

The image due to a diverging lens is always virtual and is located between the object and the lens.

Thus, the sick figure that represents a diverging lens is I1.

05

(d) Determination of the sick figure that represents a virtual magnification

From the figure, it can be observed that I1is a virtual image due to the lens.

Thus, the sick figure that represents a virtual magnification is I1.

06

(e) Determination of the sick figure that represents a negative magnification

It is known that when the image is inverted, there would be a negative magnification.

Thus, the sick figure that represents a negative magnification is I4.

69 through 79 76, 78 75, 77 More lenses. Object ostands on the central axis of a thin symmetric lens. For this situation, each problem in Table 34-8 refers to (a) the lens type, converging C or diverging D , (b) the focal distance f , (c) the object distance p, (d) the image distance i, and (e) the lateral magnification m. (All distances are in centimeters.) It also refers to whether (f) the image is real Ror virtual V, (g) inverted I or non-inverted (NI) from O, and (h) on the same side of the lens as Oor on the opposite side. Fill in the missing information, including the value of m when only an inequality is given, where only a sign is missing, answer with the sign.

A pinhole camera has the hole a distance12cmfrom the film plane, which is a rectangle of height 8.0cmand width 6.0cm . How far from a painting of dimensions 50cm by 50cmshould the camera be placed so as to get the largest complete image possible on the film plane?

An object is placed against the center of a concave mirror and then moved along the central axis until it is 5.0 m from the mirror. During the motion, the distance |i|between the mirror and the image it produces is measured. The procedure is then repeated with a convex mirror and a plane mirror. Figure 34-28 gives the results versus object distance p. Which curve corresponds to which mirror? (Curve 1 has two segments.)

17 through 29 22 23, 29 More mirrors. Object O stands on the central axis of a spherical or plane mirror. For this situation, each problem in Table 34-4 refers to (a) the type of mirror, (b) the focal distance f, (c) the radius of curvature r, (d) the object distance p, (e) the imagedistance i, and (f) the lateral magnification m. (All distances are in centimeters.) It also refers to whether (g) the image is real (R)or virtual localid="1662996882725" (V), (h) inverted (I)or noninverted (NI)from O, and (i) on the same side of the mirror as object O or on the opposite side. Fill in the missing information. Where only a sign is missing, answer with the sign.

When a T. rex pursues a jeep in the movie Jurassic Park, we see a reflected image of the T. rex via a side-view mirror, on which is printed the (then darkly humorous) warning: 鈥淥bjects in mirror are closer than they appear.鈥 Is the mirror flat, convex, or concave?
