Question

A plane electromagnetic wave varies sinusoidally at 92.2 MHz as it travels through vacuum along the positive x direction. The peak value of the electric field is 2.12 mV/m, and it is directed along the positive y direction.

I need help with parts E, F & G please!!

Part a.) is 3.25m

Part b.) is 10.8ns

Part c.) is 7.06pT

Explanation / Answer

Wavelength (?) = Speed of Light (c) divided by the Frequency (f)
? = c / f
c =..meters per second (m/s)

? = (c m/s) / (92.2E6 Hz)
? =.3.25 meters (m)

Period (in seconds) = 1 / f
1 /92.2E6 = 10.8ns
