Electromagnetic fields and therefore waves are generated orthogonal to the electric current that generated it.
There is no image or choices so what exactly do you want us to answer.
If you are talking about frequency in terms of waves, it is in seconds^-1
Using the Punnet square, you find it is a 100% chance
