(adsbygoogle = window.adsbygoogle || []).push({}); 1. The magnetic field of an electromagnetic wave in a vacuum is B_z= ( 3.0 uT )*sin(( 1.00*10^{7})x - omega*t) , where x is in m and t is in s.

What is the wavelength and frequency of this magnetic wave? What is the amplitude of the E field?

2. wavelength = 2pi/k

frequency = f = 1/T = omega/2pi

E = cB

3. k = 1*10^{7, so lambda = 2pi/k = 6.28*10-7}

How do I find frequency without knowing omega?

How do I go about obtaining an actual value for E_{0}? It doesn't seem like E =cB will be enough here...
