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…
Light coming from a fish makes an incidence angle of 30° to normal under the water. The index of refraction
of water is 1.33. A fisherman is looking at the fish through air. At what angle with the normal (6, ) will the fish
appear to the fisherman? Use Snell's law: n, sin e, = n, sine,
Using Snell's law, solve for the index of refraction of air computed and % difference of the index of refraction.

Below, you glimpse a path that light takes through a clear block that has an index of refraction of 1.20. Using a ruler and protractor, draw the path that light will take as it goes 1) into the block, 2) out of the block, as well as 3) the path some of the light takes when it reflects off of the bottom interface (recall that at this interface, some light reflects and some refracts). block airarrow_forwardIntegrated 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…arrow_forward
