How is the phase shift of light measured? Not quite what I had in mind, but thanks for the input. It's an interesting process I'll have to read up on. |

E and H fields created by fiber optics? Thankyou. Very helpful. Almost feels like a "see the forest for the trees" conundrum. Light is an EM wave, which is the propagation of electromagnetic energy, which kind of makes the whole question moot. Thanks again. |

In electro-optic material, what is happening to the structure of the material for the index of refraction to change? Thanks for the book recommendation. After reading a sample, I found a used copy to order. |

Is the acceleration and deceleration of a wave instantanious? I understand. It's not the the light slows down, the excited states of the medium "hold on" to the light for a brief amount of time, leading to an aggregated slowing of the propagation of the wave. So is this what is meant by absorption and re-emission of light through a medium? |

Falling into a black hole I think I agree with your statement in 2. As you are looking back at the outside observer, you would see the observer rushing away from you at an increased velocity. Eventually, the observer will be beyond your observable universe (like you said, you are moving away faster than the observers light can reach you.) |

Why does laser light not affect glowing materials? Fantastic. That is very interesting. I will attempt phase two of the ball / light experiment with blue filter analog. |

How to find the value of the parameter $a$ in this transfer function? yes sorry, I did that math wrong, corrected now. It's funny you asked this question. I am doing a feedback control class right now and am covering this same material. |
