Answer:
a
The direction of the wave propagation is the negative z -axis
b
The amplitude of electric and magnetic field are ,
respectively
Explanation:
According to right hand rule, your finger (direction of electric field) would be pointing in the positive x-axis i.e towards your right let your palms be face toward the direction of the magnetic field i.e negative y-axis (toward the ground ) Then anywhere your thumb stretched out is facing is the direction of propagation of the wave here in this case is the negative z -axis
The Intensity of the wave is mathematically represented as
Given that
Making the subject we have
Substituting values as given on the question
The amplitude of the electric field is mathematically represented as
The amplitude of the magnetic field is mathematically represented as
Substituting value
