$\cdot$ The electric field of an electromagnetic wave points in the positive $y$ direction. At the same time, the magnetic field of this wave
points in the positive $z$ direction. In what direction is the wave
traveling?

All right, so in this problem, we have this. Ah, the hostile, like magnet. So this is an s. So there's a pointy. It would have a current pointed into the paper at point P. Ah. So we have the coordinates. Why? X and Z. So you need to utilize your ah, your left hand rule. Okay, Just raise your left hand and apply that left hand rule. You see that? Ah, because the direction the current pointing into the paper and election feel that Point P is pointing down. Right? So you see that? Ah, the direction fools applied on this wire is actually pointing to this direction. Okay, so there's a negative X direction, all right?

Welcome to the problem. But thirty two point two, this's chakra electromagnetic waves number thirty two. So, in this condition of question were given that electric field directions and magnetic for directions and they propagate. So we need to find out the direction of the propagation of the faith and an accident. The propagation of the faith is in the conspirator Off Eve actor and director. So that's why we have e cap and be campaigning. So direction is because two we have for this way. So we have I jay two. So this is Portia success. That means that we feel is in X direction. So we have one zero zero and basing. Why my directions? So that means Jiro one Zito So taking the cross border. So this comes out to be What did Kate that means the direction of the population of the world. Maybe it is for d j. Alexis now going to this, But we have I can't Jacob K camp here we have minus y. So that's mean with zero minus one Jiro and basin extraction. That means one Geo geo taking the crows. Burke. So that gives again. Was it to get that mean supposed to that direction or a positive exceptions for this one? We have I can't. Jay Camp, Camp zero zero one minus one zero zero. So this gives us miners gica. That means direction is in minus y axis and going to deeper. We have I J Cap Jiro one. Jiro, Jiro, Jiro. Mine is Let me put mine. Escaped. The crossbow comes out to be minus. I can't. That means direction. Anything minus xx is so That's your answer for this question. Thank you for watching the video.

In this problem, we're given four different situations. We want to figure out the direction of propagation in each one. Now we get the direction of provocation by applying the right hand rule. So for each case, we're going to point our fingers in the direction on the electric field, and they were going to curl our fingers in the direction of the magnetic field. Once we do that, our thumb will point in the direction of propagation. And this only works if you use your right hand. So, for instance, in port, eh? We know the electric field is pointing the extraction. And so if we point our fingers in that direction and then curl upwards in the white direction, then your thumb should be pointed out at you. And that's in the positive direction. So the direction propagation for far a isn't the positives. He had direction for power. Be sorry, Bethany for Part B. We're getting this situation. Let's say this is the X axis and this is the Y axis. Then we're told the electric field points down this way in the magnetic field. Points this way. Sorry, I'm having to make the arrows really wide because they're overlapping on the axes. And so if we do the same thing, when our fingers in the direction of the and curl toward be again the thumb should be pointed out, asked you. And so this is again in the positive. See how direction So for Percy, Let's let the horizontal axis well, Gosh, this is terrible. Horizontal there ago be the X axis and the vertical. Here be the Z axis, and we know the electric field is pointing down positive. See direction in the magnetic field is pointing in the negative extraction like this. So again, fingers in the direction of the curl towards the and then you'll find that that the direction propagation is going into the page here and so into the pages. Actually, the positive wind direction. It's pretty hard for me to draw this on the page because it's just a right hand problem. And so, for party, we have the electric field pointing in this direction. So this is the electric field. It's that means this must be the positive Why and then the positive zis is up here in my neck feels pointing in the negatives you and then you just do the right hand rule on this again, and you come to the conclusion that it's money in the positive except direction. That's a direction propagation.

In question 16 were told that a radio waves travelling in the negative y direction and you want to know the direction of the electric field if the direction of the Mennonite feels is in the positive X direction. So there's a wave question that is to be you represented three dimensions. I'm going to invest to draw that here. So this is my really coordinate system. And this is my X axis. This is my Y axis. And this is my said, we want to find out again the conditions of the question state what, Richard me must be me direction. If the B direction of our wave is in the positive X, you know that our wave direction reef travel is in the negative y direction. So I'm putting this my native Why, which of course, would be the case for my corn insisted that I drew. Do you think of how the ways air traveling if we want our magnetic field was all drawn blue here to be traveling in this direction? These are run by magnetic field lines, you know, on my wave packet, this is B and by using our right hand rule. If we want If we're writing this out, are, um, our thumb We'll be traveling in red. So our thumb is the direction of our wave and therefore, depending what type of rule you use the second quarter. It has to be not included. Thumb their second or in a house of your being, that field pointing in this direction. Zardari curling your fingers. Or perhaps you're pointing your middle finger in that direction so your thumb would be pointing the red, your middle finger re pointing towards the blue, which only means that your index finger, your other component and reign and rule happy traveling this direction downward. What's to indicate that actually killed must be in the negatives ed direction? Look in my right hand rule. We determined that if we're traveling in the wave again is troubling. Making the negative wine all right hand will coordinate System would indicate that are in next thing air points one direction, our middle finger pointing the other direction. And there are some points that are resulting vector which will be our traveling wave. So therefore again, this has to be the negatives that direction for our electric field. There you go
