Integrated Tutorial
In a science fiction story, a major character pilots his own spacecraft, which is propelled by a stellar sail. As
shown in the figure (not drawn to scale) a stellar sail is a large reflecting sheet attached to a spacecraft, much
like an ordinary cloth sail is attached to a boat. Light from the star reflects off the sail, exerting a force on the
sail. In the story, the spacecraft is small, and the single passenger sits in a small capsule. The trip is a short
one, and there are no facilities in the capsule for rest, exercise, or nourishment. So we estimate the mass of
the spacecraft, including the passenger and the stellar sail, to be m = 7000 kg. We further estimate the area
of the stellar sail to be A = 8000 m2. Say that the mass of the star is M = 8 M, and its luminosity is
L = 2170 Le, where the subscript o stands for the Sun. The mass of the Sun and its luminosity are
1.99 x 1030 kg and 3.84 x 1026 w, respectively. Find an approximate expression for the net force…
A pure red object on a black background seems to disappear when illuminated with pure green light. Explain why.
A student is carrying out an experiment similar to Fizeau's experiment to measure the speed
of light. He sets up a mirror on one headland and a laser and photosensor on another,
3.20 km away, positioned behind a toothed wheel, as shown. The laser light reflects off the
mirror, passes between the teeth of the wheel and reaches the photosensor. The gaps between
the teeth on the wheel are 6.00 mm wide.

During the night, the angular velocity of the toothed wheel is gradually increased from zero
until the photosensor records no light. The student measures the speed of the teeth on the
wheel to be 200 ms¹ at this point. Using this information, what should the student calculate
the velocity of light to be?

- Two light sources of identical strength are placed 10m apart. An object is to be placed at a point P on a line l, parallel to the line joining the light sources and at a distance d meters from it (see the figure). We want to locate P on, so that the intensity of illumination is minimized. We need to use the fact that the intensity of illumination for a single source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source. a) Find an expression for the intensity l(x) at the point P. b) If d = 5m, use graphs of l(x) and l'(x) to show that the intensity is minimized when x = 5m, that is, when P is at the midpoint of l. c) If d = 10m, show that the intensity (perhaps surprisingly) is not minimized at the midpoint. d) Somewhere between d = 5m and d = 10m there is a transitional value of d at which the point of minimal illumination abruptly changes. Estimate this value of d by graphical methods. Then find the exact value…arrow_forwardWhen the sun is either rising or setting and appears to be just on the horizon, it is in fact below the horizon. The explanation for this seeming paradox is that light from the sun bends slightly when entering the earth’s atmosphere, as shown in Fig. Since our perception is based on the idea that light travels in straight lines, we perceive the light to be coming from an apparent position that is an angle d above the sun’s true position. (a) Make the simplifying assumptions that the atmosphere has uniform density, and hence uniform index of refraction n, and extends to a height h above the earth’s surface, at which point it abruptly stops. Show that the angle d is given by as attached. where R = 6378 km is the radius of the earth. (b) Calculate d using n = 1.0003 and h = 20 km. How does this compare to the angular radius of the sun, which is about one quarter of a degree?

She said: "I can see the book cover as blue because light from the sun travels in straight lines to the book. The white light from the sun contains red, green, and blue light. When it strikes the book cover, the blue light is reflected at equal angles, while the rest of the colors are absorbed in the book cover. The reflected blue light then enters my eye, and I see the book cover as blue." Evaluate her explanation to determine whether it is good or poor, by choosing one of the following responses: O It is problematic because the idea that "the white light from the sun contains red, green, and blue," is not correct. It is problematic because the idea that "mostly the blue light energies are reflected at equal angles," is not correct.
