Question

quick answers, no need to show work. 1. The Brewster angle B is defined as the incident angle i at which there is no reflection or =0. The Brewster angle of an EM wave hitting an oil surface is B=60o . The absolute value of the reflection coefficient at 30o a. Equals zero b. Equals 0.5 c. Equals 1 d. Can be any number <1 2.Since a current will produce a magnetic field around it, if we put a good-conducting wire connected in parallel with a 50- load in a magnetic field then a. Surely there will be an electric current flowing through the load b. There will be an electric current flowing through the load only if we bend the wire to a circular shape c. There will be an electric current flowing through the load only if the magnetic field is varying d. There will be an electric current flowing through the load only if the magnetic field is strong enough

Explanation / Answer

Ans:(1) d. Can be any number <1

Ans:(2) c. There will be an electric current flowing through the load only if the magnetic field is varying.
