    title: Problem Set 9

    (9.6)

    {:.question} Solve the periodically forced Lorentz model for the dielectric constant as a function of frequency, and plot the real and imaginary parts.

    (12.1)

    (a)

    {:.question} How many watts of power are contained in the light from a 1000 lumen video projector?

    (b)

    {:.question} What spatial resolution is needed for the printing of a page in a book to match the eye’s limit?

    (12.2)

    (a)

    {:.question} What is the peak wavelength for black-body radiation from a person? From the cosmic background radiation at 2.74 K?

    (b)

    {:.question} Approximately how hot is a material if it is “red-hot”?

    (c)

    {:.question} Estimate the total power thermally radiated by a person.

    (12.3)

    (a)

    {:.question} Find a thickness and an orientation for a birefringent material that rotates a linearly polarized wave by

    9090^\circ
    . What is that thickness for calcite with visible light (
    There was an error rendering this math block. KaTeX parse error: Undefined control sequence: \si at position 21: …da \approx 600 \̲s̲i̲{nm}
    )?

    (b)

    {:.question} Find a thickness and an orientation that converts linearly polarized light to circularly polarized light, and evaluate the thickness for calcite.

    (c)

    {:.question} Consider two linear polarizers oriented along the same direction, and a birefringent material placed between them. What is the transmitted intensity as a function of the orientation of the birefringent material relative to the axis of the polarizers?
