量子化、多普勒频移和通过光子计数的不变性实现的光速不变性:一个有趣的教学问题
Quantization, Doppler shift and the invariance of the speed of light via the invariance of the counted numbers of photons: An interesting pedagogical problem
摘要:
我们表明,当观察者位于一个平面电磁波它不是强制性的,他们考虑到时间膨胀和长度收缩的影响时,波检测从两个惯性参考系在相对运动。我们还说明了使用爱因斯坦类型的观察者面临时间膨胀和长度收缩效应的方法和使用观察者检测到达其位置的能量信息的非常规方法之间的差异。
英文摘要:
We show that when the observers are located in a plane electromagnetic wave it is not compulsory for them to take into account the time dilation and length contraction effects when the wave is detected from two inertial reference frames in relative motion. We also illustrate the difference between the approach that uses Einstein type of observers confronted with time dilation and length contraction effects and an unconventional approach that uses observers detecting information from the energy that arrives at their location.
