An X ray and a the red light from a laser     have the same frequency.     are types of electromagnetic waves.     need krypton to be produced.     have nothing in common

4. An elliptically-polarized plane wave propagating along the z-axis scatters from an electron. The E-field of the wave is given by Ē = Eo [cos 0 cos(kz - wt) + sin 0 sin(kz - wt)ŷ], where 0 ≤ 0 ≤ π/2. a. Neglect the magnetic force-ev× B. Characterize the radiation scattered by the electron by determining the frequency and the polarization along the x-, y, and z-axis. Find a direction along which the radiation is circularly polarized. b. Calculate the total scattered power, averaged over a cycle, and discuss its dependence on 0. c. Calculate the B-field and evaluate the ev× B term. Discuss the direction and frequency of the magnetic force and its dependence on 0. d. Discuss how the scattering of the incident wave is modified by the magnetic force by specifying which new frequencies are observed, in which direction and with which polarization, and the modification of the scattered power.

c) Max Planck proposed his constant h to relate the energy of a photon to its frequency. Calculate the energy in eV of red light of wavelength 620 nm.

What is the essential difference between gamma rays and green light? A. Gamma rays have an electric field, green light do not. B. There is no essential difference in the nature of gamma rays and green light other than he difference in frequency and wavelength. C. Greenlight undergoes refraction, gamma rays I do not D. Gamma rays are a form of radiation, green light is not E. Greenlight is the beam of photons, gamma rays are not photons
