What is the peak strength of the Electric Field

Click For Summary
SUMMARY

The peak strength of the Electric Field in an electromagnetic wave can be calculated using the relationship between the rms strength of the magnetic field and the speed of light. Given a magnetic field (B) with an rms strength of 7.75 × 10−9T and a frequency of 80.0 kHz, the peak Electric Field (E) is determined by the formula E = c * Brms, where c is the speed of light (3.00 x 108 m/s). This results in a peak Electric Field strength of approximately 2.33 × 10−1 V/m.

In an EM wave traveling west, the B field oscillates vertically and has a frequency
of 80.0kHz and an rms strength of 7.75 × 10−9T. What is the peak strength of the Electric Field.


So I worked this problem and got it wrong earlier and am looking for explanation as to why.

To Solve this problem, you would multiply the rms strength by 3.00 x 10^8 m/s right?



Thanks!

What is the factor difference between peak of a sinusoid and the rms of a sinusoid in general?
