2 1. A wave is incident from region 1 to region 2. The standing wave ratio in region 1 is found to be 3. Which of the following statements are true? CE A) The reflection coefficient is 0.50. B) The fraction of power reflected is 50%. C) The fraction of power reflected is 25%. D) The fraction of power transmitted to region 2 is 50%. E) The fraction of power transmitted to region 2 is 75%. 2. Which of the following statements are true for a transverse electromagnetic wave? BC A) The wavefront is always perpendicular to the electric field vector E B) The wavefront is the plane of constant phase C) The wavefront is always perpendicular to the wavenumber vector k D) The wavefront is always parallel to the wavenumber vector k E) The wavefront is always perpendicular to the magnetic field vector H 3. An EM wave is incident onto a perfect conductor. Which of the following statements are true? BCD A) Part of the wave is transmitted into the conductor. B) The electric field amplitude at the surface of the conductor must be zero. C) A standing wave exists in the region of space in front of the conductor. D) The space between the adjacent maxima of the standing wave is equal to half of the wavelength of the incident wave. E) The standing wave amplitude may not be zero at any points. 4. A dielectric slab, with impedance η and thickness d , is placed in vacuum. A uniform plane wave is normally incident on the slab. The wavelength is λ in vacuum. Which of the following statements are true? E A) If d= λ , there will be no reflection. B) If d=
