wavelength
波长
The distance between two corresponding points of consecutive waves, such as from crest to crest.
- 1.
The length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency.
波的一个完整周期的长度,从一个波峰或波谷到下一个的距离,常以λ表示,等于波速除以频率。
- 2.
the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave
波在传播方向上相邻两个同相点之间的距离
- 3.
A person's attitude and way of thinking as compared to another person's.
一个人与另一个人相比的态度和思维方式。
- 4.
a shared orientation leading to mutual understanding
共同的取向导致相互理解
