Because it also can be apart of the milky way galaxy
Answer:
Direction of wave traveling is +X direction.
Explanation:
Given :
Direction of electric field = direction
Direction of magnetic field = direction
We know that electromagnetic waves is transverse wave.
The direction of electric field and magnetic field are perpendicular to each other.
So we write,
Where direction of propagation.
Put the direction on above equation,
From the right hand rule we can say that direction of wave propagation is +X direction.
I think it is D because gas particles move the fastest but if not then it is A
Well i think the answer is impossible to find because there is no picture
