Misaligned Mirror on Michelson Inferometer Oops! Sorry the above comment should read "doesn't" NOT "does". Fat fingers. |

Misaligned Mirror on Michelson Inferometer I'll give you a hint. It does matter which mirror is misaligned. |

Is emission/absorption of a photon lossy? Or if the material is rough (think of powdered glass) then the photon energy will go purely into heat. |

Is emission/absorption of a photon lossy? Think about what you mean by "incapable of absorbing". That means the 'target" is transparent to that wavelength. In an ideal world the answer is no, in real life imperfections will lead to some loss. And if there is an index of refraction change (almost certainly is) then a certain number of photons will be reflected and a certain amount transmitted at the boundary.-> fresnel eqn's. |

Is emission/absorption of a photon lossy? It is not at all misleading. There is always conservation of energy. If you apply that uniformity the answer is always NO - there is never any loss. So why ask the question? I assumed the person didn't want an tautological answer and that had some fundamental understanding and was asking amore interesting question. So I'll be more explicit and rephrase the question as " is Absorption and re-emission lossy or not". Keep in mind that if you have emission then there must be an electron involved - reflection is something different (even though it does involve electrons). |
