Chapter 34: Q. 1 (page 989)

Suppose you have two pinhole cameras. The first has a small round hole in the front. The second is identical except it has a square hole of the same area as the round hole in the first camera. Would the pictures taken by these two cameras, under the same conditions, be different in any obvious way? Explain.

Short Answer

Expert verified

No, they will not be significantly different.

Step by step solution

01

Uses of pinhole photography

Pinhole photography is frequently used to capture the sun's movement over time. Because pinhole cameras are difficult to detect, they are sometimes used for surveillance.

02

step 2:pinholes definition

Pinholes are, by definition, so small that their dimensions are rarely important. There may be minor differences in image quality, but the overall tendency of image formation will be the same regardless of the shape of the pinhole.

aUse ray tracing to find the position and height of the image. To do this accurately, use a ruler or paper with a grid. Determine the image distance and image height by making measurements on your diagram.
b Calculate the image position and height. Compare with your ray-tracing answers in part a.

There鈥檚 one angle of incidence 尾onto a prism for which the light inside an isosceles prism travels parallel to the base and emerges at angle 尾.

a. Find an expression for 尾in terms of the prism鈥檚 apex angle 伪and index of refraction n.

b. A laboratory measurement finds that 尾= 52.2掳 for a prism shaped like an equilateral triangle. What is the prism鈥檚 index of refraction?

The illumination lights in an operating room use a concave mirror to focus an image of a bright lamp onto the surgical site. One such light uses a mirror with a 30 cm radius of curvature. If the mirror is 1.2 m from the patient, how far should the lamp be from the mirror?

To determine the focal length of a lens, you place the lens in front of a small lightbulb and then adjust a viewing screen to get a sharply focused image. Varying the lens position produces the following data:

Use the best-fit line of an appropriate graph to determine the focal length of the lens.
