物理学有关波的那部分有讲到coherent是什么?
two monochromatic sources of the same frequency and with any definite,constant phase relationship(not necessarily in phase)are said to be coherent..

Answer 1

coherent就是相干波
two monochromatic sources of the same frequency and with any definite,constant phase relationship(not necessarily in phase)are said to be coherent意思是“频率相同,振动方向相同,相位差恒定的两列简谐波叫相干波”.
相干波在传播过程中,在空间相遇.在重叠处两列简谐波所引起的质点的简谐运动具有相同的频率,相同的振动方向.由于各点的相位不同,振幅也不尽相同.
