34. A certain light wave is generated by a charge oscillating on the x axis of some coordinate system. Which of the following statements may be true?


Statement A: The light propagation is along the z axis.


Statement B: The light propagation is along the y axis.


Statement C: The light propagation is along the x axis.


Statement D: The light propagation has a component along all three axes.


a. Only statement A may be true.

b. Only statement B may be true

c. Only statement C may be true.

d. Both statements A and B may be true.

e. Statement D may be true.



35. Identify which list of characteristics is true for the light wave shown in the sketch below.

a. UV light with a frequency of 4.0x1014 Hz

b. Red light with an amplitude of about 500 nm

c. Infrared light with a frequency of 4.0x1014 Hz

d. Infrared light with a frequency of 2.2x1014 Hz

e. UV light with a frequency of 2.2x1014 Hz



36. The sketch of the light wave in the previous problem shows the wave at an instant of time (arbitrarily called t = 0). At which of the following times would the wave amplitudes have the same values shown for each position if compared to the amplitudes when t = 0?


a. At t = 7.5 x 10-15 s

b. At t = 3.0 x 10-15 s

c. At t = 2.0 x 10-15 s

d. At t = 8.2 x 10-15 s
