If the speed of light in physics were infinite, time ___ stand still. A. would B. should C. could D. might 相关知识点: 试题来源: 解析 A。如果在物理中光速是无限的,时间“将会”静止。这是对现在情况的虚拟假设,用“would”。“should”通常表示应该;“could”表示能够,强调能力;“might”表示...
This paper features an indirect method to measure the speed of light. First, the electrical permittivity of air ε0, is obtained, by using a capacitance meter to measure the capacitance of a parallel-plate capacitor, by varying the separation between its plates. By means of a least squares ...

Special relativity prevents any object with mass travelling at the speed of light, and the principle of causality – the notion that the cause comes before the effect – is used to rule out the possibility of superluminal (faster-than-light) travel by light itself. However, a pulse of light...

of science, as they have a broad knowledge of the different areas. Everything around us is physics. Therefore, we must study physics in order to understand natural phenomena. To know why and where thunder is born, what the law of gravitation is, why the speed of light is faster than ...
Changing characteristics of light-driven molecular motors during their action is an unsolved problem. Here, the authors propose to use coupling with photon confined in an optical cavity to manipulate the speed of rotation of molecular motors. ...
