What Is the Peak Value of the E-Field If the Magnetic Field Is 2 x 10^-7 T?

Click For Summary
SUMMARY

The peak value of the electric field (E-field) in an electromagnetic (EM) wave can be calculated using the formula E = cB, where c is the speed of light in a vacuum (approximately 3 x 10^8 m/s) and B is the peak value of the magnetic field. In this discussion, the magnetic field is given as 2 x 10^-7 T, leading to a calculated E-field of 60 N/C. The calculation is confirmed as correct by participants in the forum.

Hi,

My Question:

If the peak value of the magnetic field of an EM wave is 2 x 10^-7 T. Calculate the peak value of the E-field.

Work:

C=E/B so,

3*10^8 m/s=(E)/(2*10^-7 T)
(3*10^8 m/s)(2*10^-7 T)=E

E= 60 N/C

Is this right ?

Thank You

Hi,

I'm sorry but I just wanted to know if I did this problem correctly

Thank You
 
Yea that's correct.

E = CB
