Question
Constants Part A In an EM wave traveling west, the B field oscillates up and down vertically and has a frequency of 89.0 kHz and an rms strength of 7.55 × 10- T, Assume that the wave travels in free space What is the frequency of the electric field? Express your answer to three significant figures and include the appropriate units. 1 Value Units | Submit Request Answer Part B What is the rms strength of the electric field? Express your answer to three significant figures and include the appropriate units. ErmsValue Units Submit Request Answer Part C What is the direction of its oscillation? The electric field oscillates along the horizontal north-south line The electric field oscillates along the horizontal west-east line The electric field oscillates vertically None of the above Submit Request AnswerExplanation / Answer
a)
The frequency of two waves is same .Therefore
f=89 kHz
b)
Electric field
Erms=CB =(3*108)(7.55*10-9)=2.265 V/m
c)
The electric field oscillates along the horizontal north-south line
