The explanation given in your textbook for the color of the setting Sun should apply equally well to the rising Sun, since sunlight travels the same distance through the atmosphere to reach your eyes at either sunrise or sunset. Typically, however, sunsets are redder than sunrises. Why? (Hint: Particles of all kinds in the atmosphere contribute to scattering.)
You are in a room lit only by yellow light. A pillow in that room looks red you. (your eyes red +
green light as yellow, your eyes see red + blue light as magenta; your eyes see green and blue
light as cyan)
a) What colors of light is the pillow reflecting in the yellow room? What colors of light is the
chair absorbing in that room? Explain
b)
You then move the pillow into a room lit only by blue light. The pillow now looks blue.
What colors of light is the pillow reflecting now? What colors is it absorbing? Explain
c) What color will the pillow be in the sunlight? explain

Why?
From fireworks to stars, the color of light is useful in finding out what's in matter. The emission of g
by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms.
Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be
identified by heating or burning the materials and examining the color(s) of light given off in the form of
bright-line spectra.

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
