Suppose you measure the electric field of an EM wave and find that its peak strength is 63 V/m. What would the rms value of the electric field be for this wave?
Added by Jonathan Z.
Step 1
For a sinusoidal wave, the rms value is related to the peak value by: rms value = peak value / sqrt(2) So, for our wave with a peak electric field strength of 63 V/m, the rms value would be: rms value = 63 V/m / sqrt(2) ≈ 44.6 V/m Show more…
