Question

Select the correct choice or choices for each of the following. Note well that mere may be more than one correct answer to some-you must choose ALL of the correct answers for lull credit. Note that each answer is standalone unless otherwise noted. This means that if both options "a)" and "b)" are needed for the answer to be correct, but neither is correct on its own, then neither "a)" nore "b)" is correct. On the other hand, if "a) is correct on its own, and "b)" is also correct on its own, then you must circle both "a" and "b)" to get full credit unless otherwise noted. Worth 5 points each, 20 points total. Choose 4, and I will only count the first 4 you do. MC1. Conservation of energy requires that if light passes through an interface without reflection or absorption, then the incident intensity and the transmitted intensity must be equal. Given that this is the case, determine the ratio of the electric field strength E to that of the magnetic field strength B for light when it is in glass whose refractive index is 1.45. a) (E/B)_glass = C_0 almostequalto 2.998 times 10^8 m/s b) (E/B)_glass = 1.45 c-0 c) (E/B)_glass = (1/1.45)c_0 d) (E/B)_glass = Squareroot 1.45 c_0 e) None of the above MC2. The following diagram shows a flat rectangular surface in a magnetic field oriented as per the arrows shown.

Explanation / Answer

E/B = speed of light

so, (E/B)glass  = speed of light in glass = (1/1.45) c0

option (c).
