Answer -
(a) Fromthe given electric field vector, it can be inferred that the electric field isdirected along the negative x direction.Hence, the direction of motion is along the negative y directioni.e.,
.
(b) Itis given that,

The general equation for theelectric field vector in the positive x directioncan be written as:

On comparing equations (1) and(2), we get
Electricfield amplitude, E0 = 3.1 N/C
Angularfrequency, ω = 5.4 × 108 rad/s
Wavenumber, k = 1.8 rad/m
Wavelength,
= 3.490 m
(c) Frequency of wave is given as:

(d) Magneticfield strength is given as:

Where,
c =Speed of light = 3 × 108 m/s

(e) Onobserving the given vector field, it can be observed that the magnetic fieldvector is directed along the negative z direction. Hence, the general equationfor the magnetic field vector is written as:
