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.)
A metallic sphere A of radius 'R' is completely enclosed by a metallic spherical shell 'B'
(made up of same material) of inner radius '2R' and outer radius '4R'. Outer surface of B is
highly polished and is perfectly reflecting. Inner surface of 'B' and outer surface of 'A'
behave like black bodies. Initially A is emitting radiations of maximum intensity near
wavelength 2 and B is emitting radiations of maximum intensity near wavelength 62.
After sufficiently long time, both will emit radiations of maximum intensity corresponding

- In Figure P37.52, suppose the transmission axes of the left and right polarizing disks are perpendicular to each other. Also, let the center disk be rotated on the common axis with an angular speed . Show that if unpolarized light is incident on the left disk with an intensity Imax, the intensity of the beam emerging from the right disk is I=116Imax(1cos4t) This result means that the intensity of the emerging beam is modulated at a rate four times the rate of rotation of the center disk.

- The dispersion curve of glass is the curve that describes how the index of refraction of glass changes as a function of the wavelength. This curve can be represented approximately by Cauchy's empirical equation, n = A + B/2² where for a specific glass in question A = 1.40 and B = 2.5 × 10 nm² (yes, those units are nanometer squared).

- A beam of white light is incident on a slab of dense flint glass at an angle of incidence of 60°. Flint glass, as with most materials, displays a dispersion where the refractive index is a function of the wavelength of incident light. We can often write this dispersion using the Cauchy relation n(2)=A+B^(-2). For the case of Flint glass, A = 1.728, and B = 0.01342 µm2.
