Hello tony8. Welcome to PF !

What have you tried?

Where are you stuck?

I see that you're relatively new to PF. According to the rules of this forum for Home Work Help:
...

NOTE: You MUST show that you have attempted to answer your question in order to receive help. You MUST make use of the homework template, which automatically appears when a new topic is created in the homework help forums. Once your question or problem has been responded to, do not go back and delete (or edit) your original post.
...

On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given. Under no circumstances should complete solutions be provided to a questioner, whether or not an attempt has been made.
So you see, ours hands are tied until you show us something.

I think the EM wave would totally reflect
I am confused why b will affect the reflected wave
