In a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of frequency 115.0 MHzMHz in opposite directions inside a narrow cavity with reflectors at both ends, causing a standing wave pattern to occur. A. How far apart are the nodal planes of the magnetic field? Answer in meters
B. If the standing wave pattern is determined to be in its eighth harmonic, how long is the cavity? Answer in meters

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
