Laser light of wavelength 600 nm travels through vacuum in the
+x direction and at some instant of time
the magnetic field of this wave
points in the -z direction at point P. At which values of time
after this instant does the electric
field at P point in the -y direction?

b. 4 x 10-15 seconds
c. 1 x 10-15 seconds
d. 2 x 10-15 seconds
e.
more information is needed to determine which, if any, of
the above times are correct
